Ther BlackBerry 8520 (code-named Gemini). Optical trackball? The Boy Genius Report is announcing that the handset is going to hit T-Mobile USA in Q4 of this year, obviously don?t have a price yet, it?s definitely aimed at the low-cost/emerging market segment, so it?s a bit odd T-Mobile USA will carry it out the gate, but hey, the more BlackBerry users the better, right?
