This is my unboxing and first impressions of the Pantech Matrix Pro, a Windows Mobile 6.1 Standard smartphone offered by AT&T for $179 USD on a two-year contract.
This phone has the distinctive feature of having two keyboards (12 key and QWERTY), both hidden away via a slider. It weighs 4.3 ounces, has a 2.4 inch display at 240 x 320, comes with 256 MB of ROM, and 128 MB of RAM. It also features a microSDHC card slot for expandability up to 32 GB. It's a GSM/GPRS/EDGE/UMTS/HSDPA/HSUPA phone, functioning on the 850/900/1800/1900 MHz bands for GSM/GPRS/EDGE and 850/1900/2100 MHz for 3G data. The battery is 1320 mAh, giving 3 hours of talk time and 10.4 days of stand-by time.
