I need help with my Gravity Smart, I keep getting the "Low Internal Memory" message, so I was searching through my "Running Apps" to try to delete some....I tapped on my "Messaging", then tapped on the "Clear Data" tab, thinking this would delete all of my sent & rec'vd messages. Well, it didn't, and now I cannot send any text messages. I can receive, but every message I try to send fails. Can someone please tell me what I need to do to fix this? I really do not know anything about android phones, and I am not very tech savvy, I just really need to be able to send messages!! PLEASE HELP!!!!
