Switching to an iPhone is another option that's beginning to have some appeal to me.
The problem is with Yahoo, not BlackBerry. Yahoo has to make their system compatible for BB sync. Google did it, and now BlackBerry users have great integration with Google services. I sync my contacts and calendar wirelessly to my GMail account as an online backup. Yahoo has ignored BlackBerry users for years now. In fact, I don't know of any platform that syncs properly with Yahoo.
