  8. Hi there, I’ve a bit of a problem: I’ve got a 1st generation iPhone, jailbroken and unlocked (feels almost like a relic now) and STILL on version 1.1.2 basically because it always worked, never gave me problems and I was too lazy to update and find a new version of a jailbreak.

    But now I’ve got to download some apps, mainly for communicating in the office/work stuff, that obviously aren’t compatible with my version nor my phone in general.

    So, was wondering if there are still any jailbreaks for the first iPhone and if I update the phone on iTunes b4 having the correct jailbreak how screwed up will I be…? Also: do jailbreaks for iphone4 also work for others or is the software incompatible?

  11. I have a question about Iphones before I get another one. I need to know if an Iphone is jailbroken / unlocked and I restore it in order to remove the previous owners information do I need to have an AT&T sim card in order to jailbreak and unlock again? I recently purchased one and all of the information from the previous owner is still there. I want to restore to remove her information but I need to make sure that I can jailbreak it again so that I can unlock it for Tmobile. The phone is an Iphone 3GS 3.1.3. Any help that anyone could give would be greatly appreciated.

  12. I used and I think I jailbreaked my iphone 3gs 4.3.3 because now I have Cydia. How can I find out if my phone is fully jailbreaked and how do I unlock my phone.

  23. hello,

    I’ve been using iphone 1 for the longest time. It was jailbroken to begin with and its been fine until last night when it got wet in the rain. It flickered alot in the beginning and wouldn’t turn on. When it finally did turn on (i’m guessing after the last of the water dried up), the screen has the connect to itunes symbol.

    Any help on how to get this back to working condition would really be appreciated. Thanks!
