My captivate has this weird glitch where whenever I try to reply to a text from a specific number, it returns an error that it needs a 10-digit phone number. It only glitches when I'm trying to reply to a message from him, so I can send messages just fine if I delete the conversation. My previous phone didn't have the problem, and my buddy says nobody else has either. I'm thinking maybe it has something to do with that when I first created the contact and tried to send a message, I only used the 7 digits. I've tried switching from the stock messaging to chomp sms, with no result. any other ideas?
