Tried updating an iPhone 3g from 3.0>4.1 but got this : "There is a problem with your Iphone. We’re sorry, the iphone you connected maybe be damaged and cannot be activated for service. We recommend you visit your nearest Apple store for more information." Now, I have an AT&T sim card but it won't let me activate my phone. I believe it is because my phone was jailbroken then updated causing this error? Since it didn't let me update and gave me the error message, I jailbroke and hacktivate it with redsn0w so it works...but the hacktivate disables my AT&T sim card..as in no reception. I guess the only thing to do is wait for the 5.14.02 baseband unlock to come out? I tried bringing it to the apple store, no dice due to no warranty.
