T-Mobile has recently announced two high-end versions of its Sidekick line of communication devices. The new Sidekick LX and Sidekick Slide cell phones/messaging devices build off the last generation Sidekick 3 model with updated features.

The Sidekick LX's most attractive update is the 320x240 QVGA widescreen anti-relfective display technology which is borrowed from the Sharp Aquos line of LCDs. Sharp is the manufacturer of the LX model as many spy shots of the device floating around the internet have hinted.

Other features include a 1.3-megapixel camera and a 128MB microSD card to store photos, video, and music on. Though a supposed launch date of October 24, 2007 has been set for the Sidekick LX, there are reports of auctions popping up on eBay starting at around $600. We can expect to see the Sidekick LX offered by T-Mobile for $300 with a 2-year contract. The Sidekick.com site features a timeline of events leading to the official launch of the Sidekick LX with a listing of stores included in the official launch.

The Sidekick Slide contains much of the same functionality of the Sidekick LX but will be manufactured by Motorola, a newcomer in the Sidekick game, with a screen that slides up instead of the trademark swivel screen Sidekick users are used to seeing. The Sidekick Slide is said to launch sometime early November 2007 with a cost of $200 with a 2-year contract with T-Mobile.

In related news, rapper Master P is planning to release a track called Sidekick on his upcoming album, Hip Hop History, to promote the new devices.
