Unlocking 4.0.2

[rockstar0215]

I had an iphone 3gs with 4.0.1 and jailbroke it with jailbrakeme.com. The phone broke so I had to get one from my warranty. I am a T-mobile USA user and now I am stuck without a working phone.

This new phone is a 3gs 4.0.2, a version too late to use jailbrakeme.com exploit. The pwnage tool currently out only works on previously jailbroken iphones. I obviously have no SHSH's saved either.

Is there anyway to jailbrake + unlock?

Limera1n to JB 4.0.2.
Ultrasn0w to unlock 5.13 baseband.

Does limera1n upgrade the baseband? I heard greenpoison is the better of the two jailbreaks?

Also, does bootroom matter, since I think I have a newer version?

I don't mind staying on 4.0.2. When i do limera1n will my baseband remain the same?

The jb won't update your bb.
Use limerain and stay on 4.0.2
Use ultrasnow to unlock.

Just wait for pwnagetool and use that. It is probably a better tool overall if you need to unlock.

It's iOS 4.1 that upgrades your baseband. IIRC, greenpoison doesn't work with an iOS lower than 4.1. Right now, limerain looks to be the only one that works with 4.0.2.
