HTC may be in the earlier stages of developing an extremely high-end Android smartphone, says a code string reportedly leaked on Tuesday. Possibly to launch as the Scorpion, it would use the dual-core 1.5GHz Qualcomm Snapdragon processor teased at CES and would use Android 2.2, which is likely to be the final name for the update Google has so far codenamed Froyo. One line of code also makes reference to WiMAX and suggests it might head to Sprint's 4G network.
