With the HTC One S and soon the Samsung Galaxy Note hitting T-Mobile, Magenta needs some low-end hardware to round out its lineup. Luckily, Huawei is more than happy to provide. According to internal documents spotted by TmoNews, the "T-Mobile Prism 3G" (looks like they're cutting Huawei out of the branding again) will land on the network on May 6th, this coming Sunday. This one's aimed right at the entry level.
If you're looking for a phone to wow your friends or kick back and watch a full-length movie, the Prism 3G isn't it. But if you just need something with basic functionality - or maybe something to give your kids - it might fit the bill. The 3.5-inch screen has a respectable 480x320 display, though unfortunately processor and RAM aren't mentioned. You do get a 3.2 megapixel rear camera (no front-facing cam) and a 2GB MicroSD card.
The Prism 3G runs Android 2.3 Gingerbread, and probably always will. The "3G" title means that it won't have access to HSPA+ speeds, either - the service that T-Mobile has been calling "4G" for the better part of a year now. It looks like the Prism will come in red and grey colors. There's no mention of price, but given the specs I'd estimate it to be either free on contract or under $50.
