Title says it all. I'm stuck on a "Please Wait..." dialog forever (literally). Restarts don't fix it. I can only send texts if it is in the top bar (and only if 1 text), otherwise I get sent to the "Please Wait..." dialog, Please assist if applicable.
If you have a lot of text messages saved, others have posted luck with plugging the phone in to the charger, turning off the screen timeout and then opening the Text Message application and let it process.
The text messages are being reformatted to a new display style and it might take a while for the phone to finish it.
Check out the other discussions for additional tips.
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
