TmoNews has gotten hold of some pics along with a bunch of specs and info on T-Mobiles highly anticipated G1 phone which officially gets the wraps taken off it at 10:30am EDT tomorrow.

Glancing over the specs, we can see its dimensions of 4.6 x 2.16 x 0.63", weighing in at 5.6 ounces. The HVGA display outputs a resolution of 480x320 and its memory is expandable at up to 8GB (no mention of which format yet).

Other confirmed features are a 3.1MP camera, 5 hour talktime and 130 hours in standby, along with both 3G and GPS. A little oddity has been mentioned in regards to purchasing the phone from stores; apparently it will only be sold where the stores are within a 2-5 mile radius of T-Mobile's 3G coverage areas.
