Yes, I am having the same problem. Switched from an iPhone to a Raxr Maxx. I kept my iPhone to use as an iPod. The first day after the switch I received a couple iMessages on my iPhone from other iPhone users. I turned iMessaging off and then unregistered my phone with Apple. Now, I don't get most texts from other iPhone users (not on the iPhone nor on the Droid). Every once in awhile I will receive one on the Droid, but 98% of them don't come through. I have asked my friends to make sure they send the message as a text and not a message and that doesn't make a difference. It is incredibly annoying and the main reason I am seriously considering returning this stupid phone and going back to the incredibly smooth iPhone.
