I'm tempted to cancel my account, stay with Sprint for a little while longer, but... there's been so much hassle here, and I don't want to risk the possibility that T-Mobile won't want me when number portability comes along for real in May, because I am a credit risk.
Hmm. It's still worth calling them up and asking about it, I suppose. There'll be nicer phones available in May, I bet.
 Oh yeah, and I was on hold for over an hour waiting to find this out. Their "phone number portability center" is hosed beyond belief.
