I need a little advice. My wife and I both have iPhone 16GB 3GSs bought within a week of each other in Aug 2009. They are both running v3.1.2 (7D11) iOS and have 05.11.07 baseband (Modem Firmware). I have mine Jailbroken and unlocked with blackra1n and blacksn0w since Sept. 2009 and have never had a problem and Cydia has my blobs. My wife has remained stock and has never Jailbroken her phone for fear it wouldn't be as dependable as she relies on it heavily. I have used Tiny Umbrella to backup her blobs and will Jailbreak her iPhone when I sell it or when she finally gives in.
My question is this, what do you think is the best route to take to upgrade both iPhones to v4.1 iOS (there are apps we both want but are only able to run on v4.0 or higher) and still be able to sell our iPhones after our contract expires in March 2011.
I'm not sure (and I really am confused) about what Greenp0ison will bring for 3GS owners with my 05.11.07 baseband (Modem Firmware). I'm willing to give limera1n a try if Greenp0ison leaves me behind.
Thanks in advance...
This is a very simple question to answer. You should wait for the update to PwnageTool and upgrade using a custom 4.1 firmware. You will need to jailbreak your wife's phone at 3.1.2 (I suggest using redsn0w, but blackra1n would work) before upgrading it using the same custom firmware.
This will preserve your 05.11.07 baseband and your ability to unlock the phones using ultrasn0w.
