This happens in handcent, the stock app, when receiving tweets or regular ol' texts.. I was told I need to take my Droid X into the corporate store (where they have actual (supposed) techs) to where they have to hook my phone up to THEIR system and
flash my phone. If that doesn't work, then they send me a new phone. (well, refurbished....500$ and I get a refurbished phone...) anyways, they are aware of the problem. The guy told me that the last update that was released a month or two ago was suppoed to have fixed the issue. well, it does NOT fix the issue. I did get in writing from him though that I would get a replacement phone and keep my current phone while the new one is sent out. I have his contact email and he said he'd order it for me so that another agent wouldnt have to order it and i'd have to send my phone in first and use a loaner. EIther he's really nice, OR he likes me. Jesus we could be married, we've spoken 5 times now and he calls to see if im still having the problem. Hes not a creeper, hes actually really nice. My record was 14 in a row at 3 am, it was lovely..... SOME OF THE BEST BUY ASSOCIATES ARE GOOD TECHS. BUT NONE OF THE REGULAR VERIZON STORES HAVE ANYTHING BUT CRAPPY SALES PEOPLE WHO CANT EVEN SELL ANYTHING, THEY HAVE NO CLUE. You have to go in there knowing what you want. or you are screwed. So, go to a CORPORATE store. Call them and ask them if they are corporate stores, or just call Verizon from 611 on your phone and have them tell you where they are located.
