I upgraded my T-Mobile Curve 8900 to OS 4.6.1.168 last night. Everything is working great, and the issues I was having with Slacker seem to be gone. However, when I go to delete a SMS text message, it won't delete. The BlackBerry lets me select delete from the menu, and when I confirm I want to delete the message, it returns me back to the list of messages, but what I tried to delete is still there. I've tried this with multiple messages and it won't let me delete any SMS text messages. However, when I go into my e-mail, I can delete e-mail messages from any of the three accounts I have linked to the BlackBerry just fine. Other than this one issue, everything else seems to be fine? Any ideas? I've pulled the battery and SIM card twice now with no change.
