I have an older blackberry. An 8330. I have been using google calendar sync and its been working perfectly until about 2 weeks ago it stopped syncing. It displays on the blackberry in red font "Server problem. Please try again later" that was 2 weeks ago. I have the latest O/S in the blackberry. The brouser is the latest firefox. I manually sync and it gets thru the sync but then displays the same thing. How do I know which server? Is it Google or RIM?
