iPhone: Upgrade to 2.2?
„Upgrading an iPhone 3G to iPhoneOS 2.2 without using a pwning tool may make it impossible to software unlock in the future!”
Update 1: iPhone-Dev Blog
Update 2: Ura, se poate face upgrade-ul la 2.2, da’ cititi bine iPhone-Dev Blog (II). Citez de la link-ul anterior amintit cateva detalii:
SIM Free/SP Unlocked/Factory Unlocked iPhone 3G
This applies if you bought your iPhone 3G for $$$$$$$. This model of iPhone 3G doesn’t have an Service Provider lock (aka factory unlocked) and you are able to put any SIM card into the phone and get service. Your phone is already unlocked so you do not need to worry about baseband updates, simply upgrade to 2.2 using iTunes and then use QuickPwn to Pwn and Jailbreak. This will add Cydia and Installer too.
Locked iPhone 3G – Preserve Baseband
This applies if you have a locked iPhone 3G and you wish to update to 2.2 but preserve the iPhone’s current baseband software. Preserving the baseband will give you the maximum chance for any upcoming software unlock. To upgrade your phone to 2.2 and preserve the state of the baseband you need to create a custom .ipsw with PwnageTool. This custom .ipsw will not contain the baseband update but of course will still allow all the cool new stuff from 2.2.
There are plenty of tutorials about this process on the web, but PwnageTool contains intuitive graphics and easy to follow prompts that should have you up and running in no time at all.
Locked iPhone 3G
If you are using your iPhone with one carrier and have no interest in the possibility of an iPhone 3G unlock in the near future then just restore or upgrade to 2.2 using iTunes and use QuickPwn to Jailbreak and add Cydia and Installer.
Update 3: In sfarsit, l-am updatat si eu la 2.2. L-am si jailbrake-uit cu QuickPwn!
Update 4: Am facut Restore – dupa ce in prealabil facusem backup si rulasem APTBackup – si nu mi-a reinstalat si aplicatiile instalate din Cydia ca dupa upgrade-ul la 2.1. Apple Suckssssssssss!
