Guys, this is my send post. i am stuck at my iphone4. I dont see any hope. So, i thought of doing some thing else.. I Bought iphone4 in sept-2010, since then i am waiting for unlock for bb 2.10.04 - But No luck till now. So i thought of upgrading my iphone4 to 4.2.1 w/o changing my BB . and thats where i screwed up.. though i follow all the tiny instructions... and did all correct. But, somehow , i am stuck in that Recovery Mode loop. So, what i am planning, is there a way i can upgrade to 4.3 w/o changing to my BB ? using itunes ? If possible, then i wanna gave a try. i dont know wather a jailbreak for 4.3 is available or not, but atlest i can start my iphone ( ipod ) atlest. And i am sure , jailbreak will come out fast (4.3) then UNLOCK !!!!!!!!!!!!!!((mad: Plese help me out !!
