tablet dubbed the P4100 just hit the FCC, and it appears to have AT&T LTE radios
(Bands 4 and 17) as well as the standard 850 / 1900 WCDMA bands. Interestingly enough, the device also comes with support for LTE Band 5, an 850Mhz band currently used in South Korea. The P4100 has been sighted once before in a listing of Nenamark benchmark results, hinting that it will use a 1.5GHz dual-core Qualcomm MSM8260 CPU with Adreno 220 GPU, uses a 1,024 x 720 display and runs on Android 3.2. As always, this never guarantees it'll see the light of day in the US, but having compatible LTE bands on AT&T's network -- not to mention the carrier's friendly relationship with Pantech
over the past few years -- definitely gives it a pretty high chance.
