According to an article over on phone scoop, the FCC has now made documentation public which reveal the Pantech C180 mobile phone.

The Pantech C180 is a basic GSM mobile phone which is destined for iPhone carrier AT&T as an entry level handset and is a tri-band handset with a candy bar form factor and generally resembles the Pantech C630 handset.

Feature wise the Pantech C180 offers an FM radio, a music player, and memory card expansion, but lacks a camera and Bluetooth, thus is fairly basic fare and the draft user manual mentions Media Net so it has a WAP browser.
