Getting the T-Mobile BlackBerry 8820 involves some serious thinking. Though service plans may be different, they both offer the same kind of 8820. The 8820 is much wider and taller, though a bit bulkier, than the Blackberry Curve. Though the keys of the 8820 are slightly larger than the Curve, the reviewer noted that the spaces between keys in the 8820 are smaller. It offers GPS support as well as Wi-Fi that works with 802.11a/b/g. The Blackberry 8800 series is well known for its lack of a camera, and the 8820 isn’t any different. On the bright side, it supports a solid line of formats for both audio and video playback, though the reviewer noted that the included headset was mediocre at best. The 8820’s built-in GPS support performed solidly when used to give turn-by-turn directions. Call quality with the BlackBerry 8820 under T-Mobile isn’t spectacular. There were instances when calls won’t connect or, if connected, the other party can’t hear you. Switching to HotSpot @Home produced better call quality. So if you have a strong T-Mobile signal in your area, or would be heavily using the HotSpot @Home service, then the T-Mobile BlackBerry 8820 will serve you well.
