How can I sync my Blackberry with various apps such as Yahoo calendar?

Hi…I am working as a programmer in Yahoo and I am associated with it since two years. There are certain changes which have been made recently by Yahoo in its calender. There are some features in old Yahoo calender which does not function with the newer version and that is the only reason, you are facing the problem. Let me first elaborate about some old features which are there in new version are Syncing with MS Outlook, group calenders are not visible, no support for weather guides and finance and widgets are also not supported by the new version.

Now as you said you have been facing problems in connecting your yahoo calender with BlackBerry 8350 but if you try to follow these instructions, I am sure you will be able to connect. First of all, you just have to visit the yahoo go website in the resource section. Now just click on the calender option and type your mobile number in the space given on the right side of your blackberry. Now go to the send links to mobile option and you will receive a message from Yahoo about your username and password. After filling whole information, click on the finish option. The program will then synchronize your address book, calendar and even your weather and sports settings.

Good Luck..
