3gs best option for Jb??

[wiseman]

Hi guys,

i have a 3gs with firmware 4.2.1(8C148) and baseband 05.15.04,
I see there are many ways to unlock an iphone depending on firmware etc.. so what is the best way to do mine?

looking to have it unlocked so i can use my new 3 sim,its o2 at the mo,

will i lose my gps if i change the baseband to an ipad one or is there a patch for this now?

thanks

O2 will unlock your iphone for free if you are a contract customer.

However if you are looking for a good sim deal you should look at giffgaff. You don't need to unlock your phone as giffgaff runs on the o2 network.
Giffgaff will give you a free ?5.00 bonus just for activating your sim providing you order from an existing member.

Calls presently 8p, texts 4p and free giffgaff to giffgaff calls and texts.
Sadly this is going up to 10p calls and 6p texts in October but it still will be one of the best deals you can get.

They also do Goodybags which are monthly packages e.g. ?10 gets you 250 UK minutes, unlimited UK texts and unlimited mobile Internet for one month. Plus, you will still benefit from our free giffgaff to giffgaff calls and texts on top of that.

I just got a 3 sim that gives me 2000 cross network calls 5000 3 to 3 calls, 5000 texts and unlimited Data(with no fair usage policy) so trully unlimited mobile internet.
Because i want to unlock it unlocked and jailbroken, i thought i may aswell try the ipad baseband setup or whichever works
