hai there. recently bought an iphone 4 a week ago but i could not get a software unlock as my baseband is not supported. I have decided to jailbreak it and run iOS 4.3.3 but I nid to know the correct firmware to download. I am currently downloading iphone3,1_4.3.3_8J2_restore.ipsw. Is this the correct download? And should i worry about my baseband (03.10.01) and iOS 4.2.1?
