First up, @evleaks has shared an image of the ZTE Warp LTE for Boost Mobile. The third ZTE Warp device to hit Boost Mobile, following 2011's ZTE Warp and 2012's ZTE Warp Sequent, we can see that this new ZTE Warp LTE sports an 8-megapixel rear camera and a trio of what looks to be capacitive navigation buttons. The phone is running Android 4.x, and judging by its name, it'll likely include support for Sprint's 4G LTE network.

The second device that's leaked today is the Huawei Valiant for MetroPCS. Like the ZTE Warp LTE, the Huawei Valiant includes Android 4.x and a set of three capacitive navigation keys on its face. Much of the Valiant's spec sheet is still a mystery right now, but thanks to the Valiant user guide (PDF link) that's apparently already been uploaded to MetroPCS's website, we know that this Huawei handset accepts micro-SIM cards and includes a microSD card slot as well as FM radio and mobile hotspot support.

Obviously there's still quite a bit that we don't yet know about both of these upcoming phones, but so far they seem like respectable additions to Boost Mobile and MetroPCS. The Warp LTE will help to expand Boost's 4G-enabled product roster, while the Valiant looks like it's got the makings of a smartphone that'll be pretty easy on the wallet. Now we wait for Boost and Metro's official announcements for these devices so that we can learn exactly what makes them tick. Stay tuned.
