The folks over at the FCC have revealed some information on an upcoming HTC phone again, this time it’s a rather interesting 4-inch device that is labeled the “PD42100″. Details are still scarce, but we do know that it’ll support CDMA 2000, GSM 850 and EV-DO Rev. A. Other features should include Bluetooth, Wi-Fi b/g/n, and possibly a 1.2GHz processor, which would make it one of the more powerful phones around, assuming that it doesn’t take too long to arrive on the market. From the pictures, it’s obvious that this phone will sport a sideways sliding keyboard, along with a removable battery. We’ll be keeping an eye for more information on this phone, so stay tuned!
