How to fix some mysterious problems.

iPhone 4, has been software unlocked with ultrasn0w since launch. Just purchased an IMEI unlock in hopes of getting new t-mobile data plan to work. Restored software, (while still preserving baseband) and phone now checks out as unlocked, and wildcardactivated on IMEI.info. However, I only get 1 bar of t-mobile signal in places I used to get 4-5 with on ultrasn0w, and still no data service. (Though i can make calls on that 1 bar.) Do I need to go ahead and let the baseband update to get the cell service to fully function? Just want to make sure, because I know there's no going back once the baseband is updated. ANY help would be greatly appreciated!

Yes, update the baseband. 1.59 is the cause of the one-bar issue. There is too great a difference between the baseband and the iOS version.

That's 4.12.01, which is only two revisions back from current, so yes. See this chart: http://theiphonewiki.com/wiki/Firmware#GSM_model_4

and you cant update the baseband to 4.12.01, you have to restore it to the baseband that comes with 6.1.3, basebands are signed, just like the ios
