I am also receiving texts repeatedly, although it has not stopped even though I recycle and reboot my phone regularly. The time gap between the repeats is approximately 1/2 hour. I can usually stop a particular run of repeats by recycling power, but it doesn't stop the problem. At least once a day, for the last 2+ months, I will get a text that will repeat every 30 minutes. I've had some repeat only 4 times; many will repeat endlessly until I recycle power. I have checked with others who have this phone with AT&T, and others who have AT&T but other phones. Quite a few people have this happening on a regular basis. I've made one (very long and unsatisfying) call to customer service, who told me it was because I was using the AT&T Messaging app without having disabled the base texting app. That wasn't true. I was no longer using the AT&T app, I had uninstalled the updates and disabled it several weeks before and was only using the base app. I recently started using another app to see if it made a difference, and it did not change.
I use my phone constantly, and this is really interfering. On the days when I'm getting quite a few text messages, the annoyance is multiplied greatly.
I am using a Motorola Atrix HD.
I have done all sorts of cleaning, dumping, etc., on the phone, uninstalling and reinstalling updates and apps that could interfere. Nothing has changed.
