On the heels of RIM adding a push API, Google is enabling some BlackBerry users to get their Gmail and Google Calendar stuff on their handsets. Don’t jump for joy just yet. There are some shortcomings that limit its usefulness. Like the fact that users have to be connecting to BlackBerry Enterprise Server instances, and those instances have to be backed by Microsoft Exchange.

Also, only 250 users per Enterprise Server instance can get their mobile Gmail on, changes made to appointments on a handset cannot be pushed back to Google Calendar. Plus, searching for Gmail messages still requires a separate app. Updates and improvements are on the way, but until then this is what you get.

If you want to track your mail, it’s usually as simple as using FedEx, UPS, or priority mail. But if you want more shipping options, and to track your mail with more accuracy, you’ve been out of luck until now. Just remember, a watched package never boils. Or, something like that.

Just stick this GPS Mail Logger in with your letter or package and you’ll be able to follow it wherever it goes. Keep in mind that this is a package worth watching because this tracker costs $695.95. Funny thing is, even when this sort of thing comes down in price and is used by many people, thereby easing the Post Office’s workload and cost, their prices still will not likely come down.
