Yes, you read the subject line right. T-Mobile To Go now has the silver Motorola Razr as a prepaid package. It's $250, which isn't too bad considering that there's no contract involved and you can unlock it fairly easily (refill with $10 or more on day 60, request a code on day 90). It's the same quad-band superphone that T-Mobile psotpaid and Cingular have, except that it comes with $15 in airtime on a T-Mobile To Go sim and the appropriate box and such stuff. With this powerful a phone on prepaid I think T-Mobile has something up their sleeve on services, and it[s looking good.
As a side note, T-Mobile now has two designer models (aka Limited Edition) of their Sidekick II device, and they too are on prepaid. The only problem is that they're $400...about $110 more expensive than the normal Sidekick II.
One last note, the nice little Nokia 6101 flip is $150 on T-Mobile To Go. Did I read it wrong or is that the same price as the phone with a 1-year contract? :)
