That T-Mobile would carry a version of the phone is nothing new, but now we know that the phone will be available sometime in May at Walmart and Microsoft stores in addition to T-Mobile's Web site and stores.
T-Mobile isn't answering questions about pricing details just yet, but Nokia said it will sell the 520 unlocked for just 139 euros without a contract. That works out to about $185 off-contract, though we'll need to wait for T-Mobile to verify its pricing.
One bummer is that the Lumia 521 will ride T-Mobile's HSPA+ network. It's speedy in its own right, but fans may be disappointed that the handset won't experience the carrier's recently launched 4G LTE network.
The521 runs Windows Phone 8 OS, and has a super-sensitive 4-inch touch screen, a 5-megapixel camera with 720p HD video support, and Nokia's full helping of exclusive apps for its Lumia phones.
