Nokia Lumia 521 to arrive at T-Mobile stores on April

The folks at T-Mobile USA are experts at leaking various documents revealing their plans for the near-future, and guess what has happened today! That's right, we have a new leaked document, which kindly lets us know that the Nokia Lumia 521 is going to land at a T-Mobile store near you on April 24.T-Mobile is still offering the Lumia 810, but starting April 24, store staff is instructed to replace the 810 dummies with ones of the newer 521.

For those who haven't followed our stories about that sweet and affordable smartphone, it has a 4" WVGA display, a dual-core 1.0 GHz Snapdragon S4 Plus processor, 5MP camera, and Nokia's trademark design. The plastic of the phone isn't as high-end as the one in the Lumia 920, for example, but it's OK, considering the $180 off-contract price-tag.
