In March my 1 year old VX9900 stopped charging. It appeared that the contacts were not connectiing or whatever. Took it to a Verizon tech shop and they couldn't fix it so I ordered a "rebuilt" replacement & kept the same battery. It lasted 3+ months and now it won't charge either. I'm pretty sure it's not the battery and I've tried 3 different chargers. Is there a problem with this model or just my bad luck? Hate to order another but really like this model.
