i have a 1st gen iphone on firmware 1.1.3 unlocked on t-mobile. the only reason i haven't updated it in so long is because i'm scared it will lock back up and i won't be able to unlock it again with the new firmware. i haven't messed around with my iphone in forever. i currently just use my iphone to talk and text. i have that tzones hack but it just gets email, i can't do anything else. i dont want to switch over to att and i like my aluminum 1st gen iphone to go with my alu macbook! if anyone is in the same situation or knows how to update the 1st gen iphone for the most recent firmware without it locking back up, let me know. i want to start using the appstore and everything. Thanks!!!
