T-Mobile already has the Samsung-built Sidekick 4G, but it may have another up its sleeves. Images of a new Android-powered Sharp phone have been leaked by Unwired View, and its slide-up screen form factor and small rounded keys definitely resemble a Sidekick. The device is rumored to offer a 3.2-inch display with an HVGA resolution, Wi-Fi, GSM/CDMA connectivity, and GPS, but other specs remain in the dark. Sharp has built plenty of Sidekicks before, so we wouldn’t be surprised to see it get in on the Android game and re-enter the U.S. market. We just hope it has more beefy hardware muscle to make any future offerings even more compelling than the already solid Sidekick 4G.
