I am using 1.9 on my 5.0 OS Blackberry 9700 and each time I reboot or battery pull my messages get pushed again and again, which is annoying. I tried sending tweets to the Blackberry_Help and Blackberry people, but the problem is still there.
Right now I am using Socialscope but I like the regular blackberry app.
Since the new update it been like that I have yet to find a way to solve it. So before I do I reboot I turn off the fb message alert in the options part.
