Hi everyone. I'm hoping some people much smarter than me can help out. So I've moved to Kazakhstan to teach and my iphone 3GS, of course, was locked by AT & T. So, I figured I would just buy another phone over here, but it was $1000 USD. YIKES! So I tried to jailbreak my iphone. I have version 4.3.4 and used this link to help me jailbreak: http://everythingapplepro.net/?p=371 I did everything the link said and it worked (including having the Cydia app open up after tethering or whatever [sorry I sound so ignorant]). Anyways, when I put my Kazakh sim card in there, it either shows 1 bar (and cannot make any calls) or sim card invalid. The carrier still says "AT & T" under my settings. Did I not jailbreak properly? Any help would be appreciated.
