It looks like the T629 has Bluetooth support, so as long as the carrier you're using doesn't block that feature, you should be good to go.
One thing you might want to check is what speaker it has. If the speaker is a typical mono cell phone speaker, you might want to get Audacity and run the sound clips you want to use as ringtones through a High Pass Filter at 100 Hz. That will protect the speaker from getting blown out by any large bass sounds that the clip may contain.
