I have an Iphone 3GS for sale, I've used this with Tmobile no problem. Has been jailbroken and unlocked using Sn0wbreeze. Running 4.3.1 on baseband 6.15.00. This was changed to it which means that you can no longer use official apple firmware only custom firmware will work (but if you want to keep the unlock this isn't much of an issue, besides it still works great with AT&T). In great physical condition with no scratches/cracks sans a few minor ones on the backside. Screen is perfect. Asking 225 OBO Trade interests: 7.62 x 25, 5.45 x 39, 9mm, 12 GA buck/slug, CZ 52 accessories, Or anything really, worst I could say is no.
