GeoHot’s iPhone 3GS Unlock

Available In: Cydia       Price: Free  

GeoHot, the developer who brought us the purplera1n jailbreak, has released his iPhone 3GS unlock, purplesn0w. Below is what he has to say about purplesn0w and instructions on how to install it. You can view the original post HERE. This unlock is said to fix Wi-Fi, Battery and Unlock failing issues experienced with the ultrasn0w unlock.

Note: This unlock is different than the unlock released by the Dev-Team (ultrasn0w).

Wifi fails? Battery fails? Unlock fails? You need purplesn0w, the geohot 3GS unlock solution. Now I know you here a lot about different colors of sn0w, but I’m here to tell you why purplesn0w is the best. First off, what is purplesn0w? It’s a soft unlock for your 3GS that I’d actually use day to day. It’s not a daemon that takes any resources, and it doesn’t add a task to your baseband. It’s very close to a true unlock. All it does is patch three files, CommCenter, lockdownd, and your wildcard activation plist (which you need, activate w at&t sim first, no hacktivation support yet). That’s it, no other files are installed. Props to Oranav for the at+xlog exploit!

A full explanation is coming soon, but I think you clever reversers out there will see what it does, and see why it’s so pristine :-) The payload is radically different from other varieties of sn0w. beta as usual, back up first.

– Be sure to have legit activated 3GS
– Disable 3G if you don’t have it (like T-Mobile).
– Add to Cydia
– Install com.geohot.purplesn0w
– Watch for success output in Cydia
– Reboot, and enjoy your unlocked iPhone

  1. it seems purple snow bricked my iphone 3gs , i rebooted my iphone after installing this software it show apple sign with processing clock like sign going round and round, it stops for a while then apple sign goes with blank screen and again come back apple sign with same processing sign , i suggest people not to use, i think i have to restore my phone now which sucks i tried hard reboot too, it didnt work. my itunes is not detecting it so i cant even restore it , i dont know wat to do?????

  2. i finally able to take my phone to dfu mode and now i m restoring it, now i have to do everything again jailbreak , install all software from cydia, ha wat a mess. I suggest people to think one more time before trying it.

  3. Yea stay away from it. It sends ur phone back to per activate. Does not unlock ur phone. U stay stuck on searching. It needs some more work. Don’t uebit yet.

  4. It didn’t do anything bad to my phone, it just didn’t unlock it.

  5. What do you do if you already have it unlocked with ultrasn0w and now I want to unlock with purplesn0w?

  6. Same has happened to me as jumbo. First reboot I got no signal. Reinstalled purplesn0w and then rebooted and just got the same spinning wheel with the Apple logo. Having to restore. I would recommend people to stick with ultrasn0w as I’ve never had a problem with that!

  7. Glad I didn’t try this… Feel bad for all of you who tested it with issues.
