In addition to checking your e-mail, you also can take advantage of services that send alerts directly to your mobile device to inform you of breaking news, stock prices, weather, appointment reminders, or other information that you desire. You can even have alerts sent to your device to let you know when you have received new e-mail or even e-mail from a specific person.
Many online services offer mobile alerts, including Yahoo! and MSN mobile. You can have MSN Mobile alerts delivered free of charge; all you have to do is set up a passport account and log in to set up the MSN Mobile to work with your device and service.
When you set up alerts, make sure that you pay attention to how often you'll be receiving them. Some carriers only allot a specific number of free messages per month, after which you'll be paying for each message you receive. Check to see how many messages you're allowed prior to subscribing to an alert service.
Having fun:
CMBW (correct me if I'm wrong), but messaging is probably one of the most convenient and fun uses for a mobile device. While e-mail may be the original "killer app," messaging is a close second, and now popular chat services like Yahoo! and MSN are expanding from the PC and onto mobile devices.
