I'm right now on a 1st gen. iPhone (8GB) running on iOS 3.1.3 (well, it was still called iPhone OS ) tomorrow I'll be getting a new iPhone 4 (32GB), that will be running on iOS 4.1 I already downloaded the IPSW of 4.3.3 and redsn0w 0.9.6rc16 because as soon as I get it I want to update it to 4.3.3 and then I want to unlock it and jailbreak it. now, can I update it normally from 4.1 to 4.3.3 before even jb'ing it? and is it straight forward when using redsn0w? or do I need to watch out for something? I know NOTHING about basebands! I'm afraid I might brick it... please, I would appreciate any help, Thank you! switching from a 8GB iPhone running 3.1.3 to a 32GB iPhone 4 running 4.3.3 (and in just 3 months will be on iOS 5).... how drastic will THAT be?!
