First, my Thunderbolt doesn't send pictures. It barely receives them but will NOT send them. I don't have great service. The 4G goes in and out but I usually always have 3G. I've tried using just service and just my Wifi but neither work. Second, my phone isn't working with the new update. When I try to install it, it shows a ! and :greendroid:. My phone IS rooted. What do I do?
