All you have to do is clear the "apn type" field of the "t mobile data" apn settings. Why bother creating a whole new apn if this much easier method works? Just curious if there's any particular advantage... Mines been working just to e using this method, as have the amazes my two co workers use. Mines rooted (worked with the new ICS Rom and gingerbread alike), and my two co workers' amazes are completely stock. This method I've used seems pretty fool proof.
