The Samsung SideKick 4G smartphone which we know is joining T-Mobile’s network will support tethering and mobile hotspot functionality. This new model is similar in form factor to the earlier version but this one also includes a 2 GB microSD card along with 1 GB of onboard memory. The handset will run Google Android OS and sports a touchscreen, 1 GHz Hummingbird processor and front facing camera. No launch dates/details yet but keep checking back for that.
