To this end, I have constructed a server that duplicates the functionality exposed by Apple’s signature server, except using “on file” results rather than live requests.

All we need, then, is to make iTunes use it. Luckily, most operating systems also have the ability to locally define bypasses on specific hostnames through a file called hosts. Using this, we can redirect requests to Apple’s signature server to Cydia.

So, open the file C:\Windows\System32\drivers\etc\hosts (Windows) or /etc/hosts (Mac OS X) and add the following entry to the bottom of the file.

74.208.105.171 gs.apple.com

Now, when iTunes thinks it is talking to Apple, it is talking to Cydia instead. Doing this will allow iTunes to access signatures already stored by Cydia’s “on file” feature.

This server will also act as a cache for any SHSH blobs it hasn’t seen, acting as an intermediary to Apple’s server. This effectively registers your device with the “on file” mechanism, which means you can now enjoy the protections of being able to downgrade your firmware in the future even if you aren’t jailbroken.

This point should be stressed: even if you don’t jailbreak, and even if you never intend to jailbreak, you should consider using the new “on file” service.

Let’s say that Apple releases an OS upgrade in the future, you take it, and they break something important. Maybe they break your e-mail account, or your todo list. Your business is now crippled.

If only you could downgrade, right? Alas, Apple won’t let you anymore. That’s where the new signature cache server comes in: by doing your restores through this server you secure your ability to not accept upgrades from Apple if the need is dire.

To view this new feature, you will need to go into the iTunes application and then the More option on the lower menu bar. Here you will see a Ringtones option in the menu. Once selected, you have the ability to view Featured, Top Tens (by genres) or Genres of ringtones.

If you see a song from the list that piques your interest, select it. This will bring you to an info page that contains the Artist, Album title, Genre and Release Date of the song. You are also able to preview the ringtone, read reviews about the ringtone and see more media by the artist (which include songs, albums, videos… etc).

You can listen to the ringtone by tapping on the ringtones title. The ringtones range from about 20 second to 30 seconds in length. Each ringtone can be quickly purchased by tapping on the purchase price which will switch to a Buy Now button.

Once you select Buy Now, you are giving the option to assign the ringtone as the default ringtone (that would be your main ringtone), assign it to a specific contact or Done which would just add the ringtone into the list of ringtones available on your iPhone. Once you have made your selection, you will need put in your iTunes password.

Voilà, a new ringtone.

However, do not update to firmware 3.1 via iTunes. We haven’t heard anything official on the 3.1 firmware update and how it affects jailbreaking and unlocking yet. We will keep an eye on the Dev-Team for more info.

“iTunes 9 plays well with already-jailbroken and unlocked devices”

“@JonathanCee @VictorBissou yep it’s safe to update iTunes if already jb/unlocked. Just don’t update iPhone firmware too!”

The Genius feature will make recommendations for new apps based on the apps you already own. It will give you a list of recommended apps and why they have recommended them. The Genius section will be located in the App Store application in the Features option. At the top of the Features page it will now have tabs for New, What’s Hot and Genius.

The second new feature is Ringtones. There will be over 30,000 ringtones available from all 4 of the major music labels. They ringtones will be sold for a $1.29 (USD) each.

Remember, you may want to hold off on updating until we have more info on how jailbreaking/unlocking will go.

This also works for free promo codes from developers. Also, remember that when you buy a song or application, all other iPhones on the same account can download them for free. This is a great way to share the cost of a game your brother or sister might also want. If you have any other questions on how this all works, please let me know!

There’s lots of drama lately about applications being pulled from the App Store. There’s all kinds of ideas why some were pulled. Some were pulled, brought back, pulled, brought back, and pulled. Unlike PhoneSaber, which is rumored to come back with Star Wars official branding, NetShare will likely never come back unless AT&T changes some things. NetShare allows your iPhone to share it’s cellular data connection over WiFi. I decided to see what I could do about getting a refund. Here’s what I did:

1. Opened the App Store in iTunes.
2. Over on the top right under quick links I clicked “Account”
3. In the middle I clicked “Purchase History”
4. I found the NetShare app in the list and clicked the arrow on the left of that item.
5. I clicked “Report A Problem” on the right hand side of the item
6. I send this email: this application was removed, I would like a refund please

I received this email in response:

Dear Douglas,

I’m sorry to hear that the application you recently purchased has been removed. I can understand how this would be disappointing for you. My name is (name removed), and I will gladly offer assistance.

You will see a store credit of $9.99 in three to five business days. You may need to sign out of the iTunes Store and then sign back in before you see the credit in your account.

Thank you for choosing the iTunes Store, Douglas. Your satisfaction is a priority for us.

Sincerely,
