hi there folks.....

ive some questions regarding upgrade/jailbreak iphone....

ive an unlocked iphone on 1.1.2 but my question is:
why the baseband is not updated to the new oneżż

now, ive read that for AT&T users the full upgrade/jailbreak can be done...
what about the ones that dont have an AT&T planżżż

can we upgrade the baseband, then restore to 1.1.1 then upgrade to 1.1.2 and then to 1.1.3żżżż

and last but not least, which one is the better guide to update to 1.1.3żżż

thanks for any answer....

Cheers!!
