New documents have recently been spotted sharing more information about an upcoming top-tier smartphone for T-Mobile. At first thought this was a T-Mo Galaxy Nexus but after taking a closer look it appears this will most likely be the Samsung Galaxy S Blaze 4G — basically a tweaked and improved Galaxy S II. More details after the break.

Some sneaky readers searching through documents showing UAProf files for Samsung phones noticed one for model SGH-T999 had recently been published. Like mention above the first thoughts were a Galaxy Nexus but with the recent announcement of the Blaze 4G that is most likely what we have here. Recently their Galaxy S II was named SGH-T989 — leading us to believe this is either the Galaxy Nexus for T-Mobile, or the Blaze 4G but most likely the latter of the two.

Original details on the Galaxy S Blaze 4G detailed a large AMOLED display but no size or resolution was given. The news also claimed a 1.5 GHz dual-core processor and 8 megapixel camera. The phone has a slight redesign over the SGSII and has a little swoop or hump on the top rather than the bottom. The UAProf files mention a 1280 x 720p HD display on board — which makes sense given most phones have sported something similar as of late.

We’ll keep digging for more information but for now it looks like T-Mo is about to get another awesome smartphone to add to the list that offers similar specs to the Nexus.
