Tried to upgrade iphone from 1.1.4 to 2.1 and failed, please help
Okay I finally decided to take the plunge and update my unlocked/jailbroken 2G iphone. (I have tmobile.)
So after hours and hours of research, this is what i THOUGHT I had to do:
1. downgrade to itunes 7.7
2. update iphone firmware from 1.1.4 to 2.1 (or something like that) via itunes
3. run Quickpwn
So after I downloaded itunes 7.7, I connected my iphone and got the followin error message: iTunes was unable to load dataclass information from Sync Services. Reconnect or try again later. I didn't think anything of this message, because my iphone still showed up on the side in iTunes.
Next, I clicked update to update my phones firmware.
When the update finished it had an itunes icon and USB cord on the phone screen.
Next, I tried to run Quickpwn and Quickpwn said that it didn't support my firmware.
I don't know where I went wrong or what do now. I tried to connect my phone to itunes to restore it or something and with my tmobile sim card in the phone it says "The SIM card inserted does not appear to be supported."
What do I do now??
