Iphone 4S Tweet sound won't change. :-(

[winman42]

I've had this problem for months. At some point I changed my Twitter notification sound to "TWEET". Now I can't change it to anything else. If I set it to another sound, or even set it to NONE, I still get the "tweet' sound whenever a Twitter message comes in. Just upgraded to ios6, hoping that would fix it, but it did not.

Anyone else having this issue? Anyone know how the heck I can fix this?

I did contact Apple support who had no clue how to fix it. The only suggest was a FULL restore. I did a full restore today, and the problem still persists.

thanks,

Win
