hi…can i just ask you to list down what are those devices that cannot be used with this jailbreak tool?

jostree October 21, 2010, 1:46 pm

I have followed the steps for my iphone 3GS 3.1.3 (jailbroken, unlocked) and got stuck on restore from the custom-built ipsw when it was roughly 95% done. iPhone is on black screen with apple logo and progress bar stuck. Did I do anything wrong? What do you suggest I do next, please?

jostree October 22, 2010, 12:11 am

Update: Launching TinyUmbrella during this frozen restore process did the trick and took i tout of the limbo and finished the JB. So, all is good here. Thanks a lot for the JB and Unlock!!!!
