Instructions to unlock iPhone 3GS on 4.1

[h4lp m3]

My iPhone has IOS 4.1 and baseband 05.14.02.
I want to unlock it for t-Mobile and (if possible) upgrade to IOS 5 so I can have iCloud but the only instructions I could find were to put iPad firmware on it.

You can only unlock by using the iPad bb.

Could I unlock it on IOS 4 without the iPad BB?
Do I lose my GPS on iPad BB?

No other option.
And yes most likely you will lose your gps functionality and comes with other negatives as well.
Up to you but it's not a great option.

If it's an AT&T iPhone then you may not be stuck flashing the iPad baseband. Your profile says your from New Orleans so I'm assuming you're in the US which means you likely have an AT&T iPhone 3GS. If the phones original contract has expired and you OR someone you know is an AT&T customer in good standing then you can have the phone factory unlocked for free. No iPad baseband issues!

Can anyone else confirm this?

Have you looked at the 5 page long thread in this very forum for confirmation?

The real question is how do they factory unlock them?
