I've been using the BlackBerry Pearl I won at CES for a month or so and am enjoying the BlackBerry experience with T-Mobile. Today T-Mobile announced the availability of the T-Mobile BlackBerry 8820, which is essentially the Curve with integrated GPS. This new BlackBerry device also supports the T-Mobile HotSpot @Home Mobile WiFi service as well. As you can see on the T-Mobile page you can buy this device now for US$349.99 after rebate and service activation. This seems to be a device for the professional though, as a digital camera is not included with the device.
Other specs include quad-band GSM/GPRS/EDGE (still no 3G love from T-Mobile), 802.11 a/b/g WiFi, Bluetooth, GPS, 320x240 display and microSD card for expansion. It weighs in at 4.7 ounces. It seems a bit blockier than the Curve and with the good accuracy of Google Maps I don't think I would pick up one of these. Maybe the Curve prices will drop enough for me to swap from my Pearl to the Curve though.
