Today the Dev-Team released an update to the unltrasn0w unlock. The update to version 0.92 is basically a bug fix.

Today we released an ultrasn0w update that fixes an issue for those running firmware 3.1.2 with the 04.26 baseband. That specific combination resulted in a missing carrier name in the upper left-hand corner of your home screen. Today’s ultrasn0w update from 0.91 to 0.92 fixes that problem (which was an important issue for roaming). You should see the update available if you have http://repo666.ultrasn0w.com as a Cydia source. Enjoy!

The carrier logo fix has been confirmed in the following 25 countries:
USA, Thailand, Austria, Trinidad, Germany, China, Kuwait, Serbia, Poland, France, Nigeria, Egypt, Pakistan, Ireland, UK, Turkey, Sweden, Switzerland, Malaysia, Hungary, The Netherlands, Bahamas, Jamaica, India, Israel, Belgium, Canada, Portugal, Denmark, Costa Rica, Italy, Chile and Argentina

Remember, ultrasn0w is an unlock for the 04.26.08 baseband if you are on the 05.11.07 baseband, you will want to use the blacksn0w unlock.

This is the low down on our tools for use with the 3.1 firmware from Apple, please read the whole post in full before attempting anything. Because of changes with Apple’s update techniques this will be a multipart release, starting with the initial release of PwnageTool for Mac OS X – this application supports the iPhone 1st Generation (2G), The iPhone 3G and the iPod touch 1G. NB: THIS DOES NOT SUPPORT THE 3GS OR NEW IPOD TOUCH. redsn0w for Mac OS X and Windows will follow sometime in the near future, please don’t bug us about it – we’ll release when we have something ready.

1.GOLDEN RULE: If you are using a 3G iPhone with ultrasn0w and rely on ultrasn0w to obtain cellular service, then you should only upgrade to 3.1 with a PwnageTool created .ipsw. – Stay away from Apple’s direct updates as described here and here please get up to speed on the whole subject by reading the information contained in these posts.
2.If you have an original iPhone (1st generation) then 3.1 unlock works with this PwnageTool release. iPhone 3G users upgrading to 3.1 will need to continue using ultrasn0w with a PwnageTool created 3.1 .ipsw
3.Please read all parts of this post before downloading and using these tools.
4.Read items 1, 2 and 3 again and again.
5.At the bottom of this post are the bittorrent files for the 3.1 capable version of PwnageTool.
6.This app is suitable for the recent 3.1 release.
7.This version of PwnageTool will NOT work for the iPhone 3GS.
8.PwnageTool WILL work for Original iPhone (1st Generation), Original iPod touch (1st Generation) and the iPhone 3G.

iphone_dev tweet – “Early adopters have found that redsn0w JB *already* works on 3.0.1 (just point it at 3.0 IPSW!) Even for 3GS & ultrasn0w.”

It seems that while we were on vacation, ultrasn0w was updated to version 0.9. The Dev-Team has quite a bit to say about this version of ultrasn0w (including how the source code from the purplesn0w unlock helped improve ultrasn0w…interesting). Anyway, below are just a few snippets from the post three days ago and the one from tonight.

Tonight:

It looks like version 0.9 of ultrasn0w fixed up the vast majority of any problems people were seeing with the 3G/3GS carrier unlock. But here’s a brief list of fixes for anyone still seeing problems:

    • Unusual battery depletion is almost always caused by people choosing to “Restore from backup” instead of “Setup as new iPhone” when iTunes asks you. This isn’t caused by either the jailbreak or the unlock, but it’s a common 3.0 snafu. The fix is to just re-run the official 3.0 restore and choose “Setup as new” this time. Your music and apps and all that will still be synced, but you’ll get rid of any conflicting wifi, bluetooth, or carrier settings. Then just re-run redsn0w and install ultrasn0w.

    • Remember, ultrasn0w works with hacktivated phones too, but don’t outsmart redsn0w into thinking you don’t need hacktivation! If you don’t plan on using an official sim, don’t activate via iTunes with such a sim. Just keep your unofficial sim at all times and let redsn0w and ultrasn0w handle hacktivation

    • T-Mobile in the USA doesn’t use the 3G frequencies that the iPhones support, so turn off 3G in Settings->General->Network. (Some T-Mobile territories gracefully hand down to Edge mode, but most do not).

    • Certain unofficial plans have limitations on whether you can make calls and use data at the same time. That’s not unlock-related.

    • Some people have installed previous versions of ultrasn0w using non-standard techniques. While the ultrasn0w 0.9 update should have removed all previous versions of ultrasn0w, these users may have outsmarted our removal. So make sure you don’t still see /usr/bin/ultrasn0w present if you’re at ultrasn0w 0.9 (which doesn’t have such a binary anymore).

    • If you don’t need or plan to update to ultrasn0w 0.9 from a previous version, you can avoid having that red badge over Cydia by removing repo666 as a Cydia source. Don’t worry, you can always add it back later If you follow us on twitter you’ll be advised of any new updates anyway.

Last but not least, many thanks to our resident blog moderators, angiepangie and Confucious. They’re doing a fantastic job helping people in the comments, and so are other volunteers. Thank you all for your contributions!

3 Days Ago:

Short Version:
ultrasn0w version 0.9 is out! We believe it solves pretty much all of the various random issues that have been reported. Its features include:

    • Works on both 3G and 3GS
    • Works on hacktivated devices
    • Works regardless of how you jailbroke your device
    • Doesn’t patch any mach-o binary whatsoever. (Doesn’t require a separate patch as each new firmware comes out).
    • Doesn’t install any additional daemon
    •    • Has no race conditions, no popups about “Missing SIM”, no network issues
    • Is almost 7000 times smaller than its nearest competition
    • Is available now via Cydia. Source repo is http://repo666.ultrasn0w.com (that last “0” in ultrasn0w is a zero!)

Long Version:
The day before yesterday, some fellow named geohot released a program called “purplesn0w” which claims to be a better unlock than our ultrasn0w unlock released last month, and our yellowsn0w unlock released 7 months ago. He was kind enough to provide source, which we naturally took apart to try to validate his claims.

We’ve found he had come up with two pretty neat ideas, one more pragmatic than the other for the iPhone. The first is a way of patching the actual text of the baseband code by copying it over to RAM and then using the MMU and page tables to have the baseband pretend it is part of the original bootrom.

Last night we released updated versions of our redsn0w jailbreak and ultrasn0w carrier unlock. These versions are now compatible with the iPhone 3GS running at 3.0. Welcome aboard, 3GS owners! (The tools of course remain compatible with all of the other platforms too.) Also last night, saurik released 3GS-compatible versions of MobileSubstrate and WinterBoard, components that enable many different add-ons and themes.

We realize we upset some folks (e.g. existing 3GS owners) with our earlier announcement that we wanted to hold onto the 3GS iBoot-family hole until 3.1 was out. Our aim there was to get as many people as possible onboard (within reason of course) before revealing the hole, since Apple will fix it immediately. But all of that became moot when the purplera1n release was made, since it uses the same hole.

For those of you who already own 3GS phones, the outlook is bright. As long as you have your personalized (signed) dfu/img3 files, you’ll always be able to jailbreak (even if you slip up and install stock Apple firmware in the future). For those of you without 3GS phones, it’s a race against the clock to use this particular hole. There’s nothing we can do about that, but we will always be looking for new holes.

There is an update to ultrasn0w, iPhone software unlock, to version 0.8. This version of ultrasn0w is said to work on the iPhone 3GS according to MuscleNerd, a Dev-Team member.

Things to Note:
    • “Ultrasn0W 0.8 (incl. 3GS support) (see Cydia).”
    • “ultrasn0w is now 3GS friendly! First cross-platform carrier unlock, thanks partly to Apple Repo details at http://is.gd/1pRGL.”
    • “The main 3GS ultrasn0w glitch on hacktivated devices is: need to do Settings->General->Reset->Reset Network settings once.”
    • “If ultrasn0w already works for you, 0.8 won’t add anything new. This 0.8 is mostly for 3GS users or 3G outliers.”!–more–>

That means that the iPhone 3GS is now unlockable. All you need to do is go into Cydia and install ultrasn0w 0.8. If you are on a hacktivated device make sure you follow the instructions above.

Here’s a brief video demonstration by @planetbeing of the iPhone Dev Team’s ultrasn0w unlock for the new iPhone 3G S. Special thanks to @Oranav for the at+xlog crash — a gift to the community that has kept on giving

Our ultrasn0w program uses the at+xlog crash as an injection vector of our unlocking payload — and it does so on the 3GS in exactly the same way as on the 3G! But this injection vector will be lost if you update to 3.1 using the official Apple IPSW, which updates the baseband. So stay away from official 3.1 IPSWs until we release the tools that let you update the firmware without updating the baseband.

Note: T-Mobile USA users should disable 3G before using ultrasn0w

How to unlock an iPhone 3G using ultrasn0w

1. Find the Cydia application on your iPhone’s SpringBoard.

2. Tap on the Cydia icon. This will open the Cydia application.

3. Select the Manage option on the lower menu bar.

4. Here you will see two options; Packages and Source. You will want to select the Sources option.

5. This will bring you to the list of sources that are already installed on your iPhone or iPod Touch.

6. To add a new source, select Edit in the upper right corner.

7. Now select Add in the upper left corner.

8. This will bring up a pop-up in which you can enter the url for the source. Do not delete the http://. Just begin typing the url after the http://. The source url needs to be typed into your iPhone/iPod Touch perfectly. The source url is repo666.ultrasn0w.com. The o in snow in actually a zero. If you put on o, it will not work.

9. Once the url has been entered, select Add Source.

10. Wait for the sources to update. Once the sources are finished updating, select the Return to Cydia option at the bottom of the page.

11. This will bring you back to the list of sources. Select Done in the upper right corner.

12. The source has now been added to your sources list. Tap on the repo666.ultrasn0w.com source.

13. Select the ultrasn0w application.

14. Select Install in the upper right corner.

15. Select Confirm in the upper right corner.

16. Wait for ultrasn0w to install. Select Return to Cydia.

17. Restart your Device (hold power and home button at the same time).

18. Your iPhone will now be unlocked. You can remove the SIM from the top of the device and insert a new one. You may need to restart your iPhone after inserting the new SIM. Below are screenshots of an iPhone with no service, no SIM, searching for service after inserting the new SIM and finally the iPhone with service after inserting the new SIM.

ultrasn0w for iPhone 3G is ready!

1. Ensure you have upgraded to iPhone OS 3.0
2. Jailbreak your iPhone 3G using redsn0w or PwnageTool (this will also install Cydia/Icy)
3. Run Cydia or Icy
4. Please add the repo repo666.ultrasn0w.com to Cydia or Icy. That last “o” is actually the number zero “0”! If you use the letter “o” you’ll get an error.
5. Search for ‘ultrasn0w’ in cydia or icy and install ultrasn0w
6. Reboot your iPhone 3G
7. T-Mobile USA users should disable 3G before using ultrasn0w
8. Enjoy

“Good news…ultrasn0w is compatible with PIN-locked sims”

“PIN-locked sims require you to enter a code before using it. Some people (often, with corporate phones) are forced to use them”

“we’re still working on ultrasn0w, w__ found a great way we can refresh the SIM without manual ejection, so just need loader+packaging now”

“Dunno how long the loader will take; can probably use most of what c1de0x and I wrote for ys, just need to find where at buffer is in mem”
