Another glitch just now...may not be specifically Gun Bros related, but it has never happened to me with any other game before, but has some apps.
Loaded up game and the touch screen was completely non-functional once it loaded. Exited game, worked fine in start screen. Loaded up game, same problems again. Exited and loaded up Mirror's Edge...no problems. Loaded up Gun Bros and again couldnt do anything. Finally just shut off my phone and rebooted it. Loaded Gun Bros and it worked. Raped.
