Y'know T-Mo has been selling non-contact discount plans (no phone subsidy) for months now? Generally at better rates then prepay? $49.99/month unlimited talk, $79.99/month unlimited talk, txt, web.

Even More Plus Unlimited Talk + Text + Web.

Um, no.

T-Mo TOS don't appear to allow tethering to 3G. They do allow tethering on Edge at no additional charge (so back down your device.) Their happy helpful customer support (really, I think they pump drugs into their air) will happily walk you through tethering on a BlackBerry, no additional cost. Tho >10GB in a billing cycle you get throttled.

That said T-Mo plans are cheapest, win JD Powers for service, are great about supporting random phones, coverage has improved considerably in the past few years, and T-Mo does lead on Android.

T-Mobile doesn't have real 3G? T-Mobile USA just DOUBLED their 3G speeds to 7.2 Mbps, and is further TRIPLING it to 21 Mbps over the next six months. With coverage to 200+ million. I think you know not of what you post.
