Sprint revealed on Monday its plans to unveil a new device later this week. In a post to its official Twitter account, Sprint said its next phone will be unveiled on Thursday, February 24th. The carrier gave no indication at first in terms of what phone it might announce, saying only, “What do you think the next new Sprint phone will be? Find out Thursday!” Initial speculation included the unnamed Android-powered QWERTY candy bar phone from Samsung spied earlier this month and the Windows Phone 7 handset Sprint subscribers have been waiting for, the HTC 7 Pro. The latter was then basically confirmed by a more recent Sprint tweet: “If you could design a brand new phone, what would it have? Ours will have a hub for gaming, music, pictures and video.” The HTC 7 Pro features a 3.6-inch touchscreen display, a 1GHz Snapdragon processor, a 5-megapixel camera and a landscape-oriented slide-out QWERTY keypad.
