Experts ! just wanted to double check, B4 i screwed up. i have iphone 4 ( FW 4.2.1 , baseband 2.10.4 , jailbroken thru Limera1n ) i am still waiting for an unlock since last 8 months !!1 But, i have just got ipad2 ( FW 4.3.1) and found the cool features, so i thought of upgrading my iphone4 to 4.3.1. Can anybody suggest me, is it possible to upgrade to 4.3.1 w/0 changing the baseband, and can it be jailbroken ? if possible, can you please post the link. I was checking on iclarified.com , and found some of the articals. but i am afraid of changing my Baseband. please post your comments ! Appreciated!
