Sure. If you're using an APN made for a sidekick or iPhone, they might look to see if you have a sidekick or iPhone IMEI. Neither your stock IMEI nor your generic Samsung IMEI match these devices and are equally likely to get you into trouble if T-Mobile gives a sh7t. From the little I've seen on Howard forums about APNs, I don't think they do.
But as someone else stated, they most definitely would block, charge, limit, or otherwise punish you via your SIM indentity, regardless of how they determine you are using the wrong APN. They aren't going to block your phone unless it's reported stolen.
