I am having the new BlackBerry Torch 9800 from the last month. And up till now I was very happy with this one. but now I am having problems in this phone. And the problem is that I am getting a message as it syncs the calendar that reads "Error Encountered. Error Code 0x80043ac9. What does this means? For that I have also tried with the so many of the suggestion but none of them are working and for that only I have also stopped the Calendar from syncing and this is working fine now. Please anyone suggest me in my case.
