Duplicate Text Messages, Verizon: DroidX2 I have a DroidX2 on Verizon and I always get duplicate text messages and it's super annoying. Is there a simple way to fix this? Or is this a carrier issue?
This does sound like a network (carrier) issue, however, do you have any applications that intercept text messages? If so, uninstall it, and see if that helps.

Edit: i just got this issue on an ICS rom. What i think it could be - your network holds the text, and tries to send it if your phone is turned off, or has no signal. It then tries to send them. After it has sent, the network doesn't actually realise it, and sends it again.
