The T-Mobile Sidekick has been stuck playing second-fiddle to smartphones in its various incarnations over the years. While an innovative piece of hardware when it first arrived, it’s since been eclipsed by the power and flexibility of proper smartphones and fell into a bit of a niche as a messaging phone for teenagers. As this phoenix rises from its ashes and is reborn as an Android device, it will finally have the capabilities it needs to be taken a little more seriously. While T-Mobile provided some details in yesterday’s press release, today some additional phone specifications have become available.

T-Mobile has confirmed to Phone Scoop that the Sidekick 4G will support both direct tethering as well as mobile hotspot modes for connecting to additional devices. The carrier also revealed that the phone will have expandable storage, in addition to the 1GB of built-in flash. You’ll receive the phone with a 2GB microSD card, which you can swap out for a larger one at your discretion. T-Mobile additionally confirmed connectivity over Bluetooth and WiFi, as well as the presence of a GPS receiver, as if those couldn’t just be taken for granted.

The 1GHz Android 2.2 smartphone will be available in a choice of colors when it arrives this spring.
