While some more high-end devices are expected at T-Mobile at around the same time like the T-Mobile G2X and the T-Mobile G-Slate, the Sidekick 4G has some decent specs as well. While the series is known for its outstanding physical QWERTY keyboards, the Sidekick 4G looks like it won't disappoint with a 5 row QWERTY. A 1GHz Hummingbird processor powers the phone which has Android 2.2 under the hood. A 3MP camera graces the back of the handset while a VGA front-facing camera allows for video chat, which you will be able to view on the 3.5 inch WVGA display. And with the 4G next to its name, the Sidekick has HSPA+ connectivity which should allow the phone to fly at speeds as high as 21Mbps.
The Sidekick has replaced the swivel design on the display with a unique hinge. An optical trackball is worked into the design of the hardware and the software now includes some social networking features like Sidekick Group Text and Cloud Text. The former allows for group text conversations similar to having a "reply-all" option while texting. The latter allows you to text your friends while on your PC.
Besides Sidekick fans happy to get a chance to buy an up-to-date version of the phone, T-Mobile also will get buyers looking for a device that comes with a multitude of features for a low price. With that in mind, a source at Tmo News says that manufacturing limitations could lead to shortages of the Sidekick 4G for the first 1 to 2 weeks after launch.
