I have an iphone 4 version 4.2.1(8C148) with firmware 03.10.01, all I want to do is Jailbreak it and not unlock it because I have AT&T. on other comments I've seen that this updates the baseband... will this void my factory warranty and applecare? thanks!!

i Jailbroke my iphone 4 [version 4.2.1(8C148), firmware 03.10.01] using the latest Redsn0w mac 0.9.7b5 but having problem with Skype not loading. I tried the jailbreak process again to see if I was not doing it right but all apps seems to working fine except Skype and Watsapp. Just wanted to inform the dev team about the glitch. Thanksks for all the great work.

Hi.. I've got an unlock iphone and it was already running 4.2.1 without JB. I tried to JB with redsn0w and followed all the steps in the tutorial, but when the iphone is doing its first reboot while in the process, it freezes.. I reboot it manually and start it back.. and i use the redsn0w app so that the phone start.. but when he starts, i don't have any network carrier :( and i can't even do a restore via iTunes, cause it says that my device isn't compatible.. how can i solve this out ? thanks!
