Check your Cydia packages and make sure Ultrasn0w is there with the green check mark. BE SURE to turn OFF 3G in Settings > General > Network. Then shut down your phone, put in your SIM (Tmobile I assume) and turn the phone back on. it might take 30 seconds to a minute, but it will work. That should do it.
