O.k. I have been reading up on all of this and it seems the more I read the more confused I get maybe I 'm just not real familiar with the lingo and what actually applies to what so....I have a 3g and unknowingly did the itunes 3.1 update, AT&T is my carrier and all I really need to be able to do at this time is use my phone for tethering internet to my laptop my firmware is 3.1 my baseband is 05.11.07 BUT my serial number YWW is Y= 8 WW= 29 so it is possible to use fuzzy downgrader to downgrade my baseband...right? Jailbreaking and all that would be cool in the future but right now my main issue is tethering so if I understand correctly it is posssible I just need to know what steps to take to do it.
