I have been away from iphone stuff recently choosing to use the Blackberry Storm but I am wondering if it is possible to upgrade my original 1st gen iphone to the latest software that is in the 3G iphone? I realise that I will not be able to use GPS or cut and paste etc... but would like the latest firmware to run on my old iphone. I have read quite a few of the posts here but not found exactly what I want to do with my iphone etc... My iphone is unlocked and I am on Orange UK network. If this is possible could someone tell me what version of firmware I would need and also what version of itunes I would need to get it all sorted, then I could and search for them and give it a go. I have restored to different versions of firmware before so I am fairly competent at doing this stuff. My iphone is currently running 1.1.1 firmware and itunes says that i can update to 2.2.1 firmware but I am not sure if I will loseor lock up my iphone if I do this. I am currently using itunes version 7. I have d/l this file already >> 'iPhone1,1_3.0_7A300g_Restore2G2.ipsw' but it says in the readme file that I need to activate my 'UDID' or it will be locked until a final release is available, but I am not sure what this means? Any advice or tips would be very welcome please! Cheers!
