First of all, the Blackberry Curve 8520 has a trackpad, which we can be sure we’ll get to see in future Blackberries. This model from Blackberry is pretty much like the Curve 8900, only that this looks like it was made for a 6-year-old because of its poorly built structure.
The corners of the Blackberry Curve 8520 are roundly cut. It has a lower resolution of 320 x 240 display screen and a plain plastic for its battery cover. It lacks a GPS (but does include a Google Map) and the camera is only 2 megapixels. T-Mobile also did not include in this Blackberry Curve 8520 the Blackberry App World, so you will have to download it yourself.
The trackpad is 90 percent better than some trackballs in mobile phones out there. You can pretty much control swiftly the trackpad so that makes for a less hassle browsing. There’s also a three-key quick access on top of the phone.
There is not much to tell about the “excellent” features of the Blackberry Curve 8520, but it does include all other standard Blackberry features. It is priced at $130 with a two-year contract with T-Mobile while you can also get it for only $49 at Wal-Mart with the same contract.
Personally, I’d much rather suggest you just do away with the Blackberry Curve 8520, and get yourself some pretty powerful Android, iPhone and WebOS but of you would like to take the risk, be my guess.
