T-Mobile is going to offer their new Sidekick LX by Sharp, and Slide by Motorola, within the next few weeks.

The Sidekick LX, otherwise known as Sidekick 4, by Sharp is said to be slimmer and weighs less than the Sidekick 3, has a 3-inch WQVGA display that is thinner and mounted on an improved swivel joint. The keyboard has a rubbery cover like the previous Sidekick 2 for a “softer” touch. The colors available are blue or brown. The LX will be available for $299 and a 2-year contract commitment.

The Motorola Slide, on the other hand, has slightly less features than the LX, and the screen slides directly upward instead. The Slide will be available for $199 and a 2-year commitment as well.

Both the Sidekick LX and Slide support GSM/EDGE and Bluetooth, comes with a 1.3 MP cameras, and microSD expandable memory.

The new T-Mobile Curve is one of the latest and coolest Blackberries around, having the “smoothness” feel to it like other Curve models. The QWERTY keyboard on the 8320 is spacious and is a tad bigger and rounder than the older ones, making it easier to type faster.

Some of the Blackberry 8320 features are: 2 megapixel camera that take clear and color-rich pictures, 3rd party instant messaging support for AIM, Yahoo, and Windows clients, Wi-Fi integration which offers fast download speeds, music player, stereo Bluetooth, 3.5mm headphone jack, and memory card slot.
