When I try to shut down my 8703e it follows the usual routine but then just sits on the Verizon wireless screen and freezes that way, I've left it over night before to see if it will work itself out but it just stays that way until the battery dies. the only way to unfreeze it is to remove the battery. It doesn't do it all the time and I cant seem to recognize a pattern so it's nearly impossible to do it on command to help understand what the problem is. has any one else had this issue??
