A purportedly leaked document has revealed a trio of new devices coming to T-Mobile, including the Samsung Galaxy S Blaze 4G, HTC Ville, and Huawei Prism. Samsung and T-Mobile have since officially announced the Galaxy S Blaze 4G, which will be coming out in March and will run Android 2.3 Gingerbread, while the other two devices will likely be officially revealed at Mobile World Congress at the end of the month.

A video of a prototype HTC Ville — reported to be a 4.3-inch dual-core handset that's less than 8mm thick — was leaked from France at the end of January, giving us an early look at what the device looks like. Meanwhile, Huawei is rumoured to be unveiling a new series of "Diamond" smartphones, which could well include the Prism. Unfortunately, the leaked document is an accessory sheet without any specs, so we'll likely have to wait until February 27 when MWC kicks off in Barcelona to learn more details.
