Can some very clever person give me some advice about my iphone?
My iphone has been unlocked and jailbroken since i first bought it, its an older phone (model A1203 / MB213B & not a 3G) its running on version 2.1
It works really great right now on an O2 Simplicity pay as you go sim and i have loads of older Apps on it.
But almost all apps that i try to add now say that my phone is "not Compatible" and "this application is not compatible with this iphone".
Can anyone advise me if i should / how to upgrade my phone?
Any advice would be greatly appreciated.
Many thanks in advance.
