New to jailbreaking and unlocking
I'm new to the jailbreaking community and wish to pointed in the right direction.
I've just obtained an Iphone 4 with firmware 4.0.2 and baseband 01.59.00.
I want to jailbreak and unlock to use with T-Mobile. I want to go to ios5 while preserving my baseband. I see a bunch of programs ending in snow or rain. I don't want to make a mistake and upgrade my baseband. Will the jailbreak and unlock be unteathered?
Any help appreciated...
