If you’ve been in suspense and can’t wait to find out more about that BlackBerry Curve 8520 with the optical trackball in place of the spinner, the folks over at CrackBerry have posted a pre-release review. Overall, it’s a pretty nice phone, and the optical trackball works well. The hardware is well put together and the OS runs smoothly.

Is it as cool as the Curve 8900? Not really. The design in general has been updated, but things like the screen, battery, and camera are from the Curve 8300. What gives? It is EDGE-only and may turn out to be a pay-as-you-go phone. We’ll see

The Sony Ericsson T707 is finally out and about and comes packed with cool light effects and gesture controls. The phone lights up when you get a call and you can personalize the light settings to each of your friends, so you know whose calling.

The T707 features a 2.2-inch, 262k color TFT (240×320 pixels) scratch-resistant display, 3.2 megapixel camera with 3.2x digital zoom, geo tagging, video recording and video light, media player with MP3/AAc support, stereo Bluetooth with A2DP, Exchange ActiveSync and Google Maps.

Lenovo unveiled its new mobile phone, named the X1. The X1 is a 3.2-inch WQVGA display, slide-out phone which uses Tri-Band and EDGE networks. Some other features are built-in GPS and a MicroSD slot for memory expansion.

As far as dimensions, the phone is a close match for the iPhone. The new X1 has a sleek look with a feather touch interface on the front panel and smooth edges. It’s a shame this phone will only be available in China for the moment.
