It may have taken a bit of time but T-Mobile has begun to offer the G1 in white. It is in extremely limited supply so if you have been holding out for it, you had better move quickly.
Powered by a 528MHz Qualcomm MSM7201A processor, the T-Mobile G1 comes with quad-band GSM/GPRS/EDGE and dual-band UMTS/HSDPA (1700/2100MHz) connectivity, a 3.2-inch touchscreen HVGA (480 by 320 resolution) display, 192MB RAM and 256MB ROM, a QWERTY thumb keyboard under the sliding display, a trackball for one-handed navigation and one-touch buttons to access popular Google applications, built-in GPS, 802.11 b/g Wi-Fi, Bluetooth 2.0+EDR (no A2DP), a 3.2MP camera, a microSD card slot (with 1GB card preinstalled) and a 1150mAh battery. It measures 11.7 by 5.5 by 1.6 centimeters (4.6 by 2.16 by 0.62 inches) and weighs 158.8 grams (5.6 ounces) with battery. It also features a digital compass and motion sensor.
As with the black and bronze versions already available, it sells for USD$179.99 with a two-year service contract.
