dear yahoo messenger expert, since yesterday 6 march 2012 about 2PM i can not sign in yahoo messenger in my BB device,the error message always "invalid user name and password"
i already insert my card into my friend's BB device and it's working(i can sign in yahoo messenger). but when i insert my friend card into my BB device, also doesn't working (i can not sign in yahoo messenger "invalid user name and password").
i also already go to BB service center and re-install my BB software and it's application. but I still can not sign in yahoo messenger ("invalid user name and password").
currently i only can sign in yahoo messenger through my PC or LAPTOP.
So please solve this problem ??
