I have AT&T until Dec 20th. Afraid of losing coverage, you know the orange ribbons covering the planet Thinking of T-mobile since thier familyplan can save me $20/month and I can get a Moto Defy or Mytouch 3G Slide with a better data plan. I do live in a 4G city (Greensboro, NC) and may be able to get the G2 or myTouch 4G if lucky. I guess coverage out in the countryside and remote areas is not as good as I have now? Who does T-mobile roam with and are there any charges?
