The Motorola V300 ($99 with a T-Mobile USA contract) has a very intuitive interface for sending and receiving e-mail via phone. With it, you can also take pictures and send them to your friends—and unlike with Sprint PCS, you can attach a picture to an e-mail message.

Unfortunately, you can't set the phone to collect POP3 e-mail directly. To access POP3 mail or your corporate mail, you need t-zones Pro (unlimited usage, $9.99 a month). You can set up this service to collect from different POP3 accounts and even your Exchange or Notes mail.

If your company is running the Web mail client of either Exchange or Notes, T-Mobile can connect to it to retrieve your mail and calendar. If not, you can download an application, just as with Sprint PCS, to run on your computer and access corporate mail from your phone. The service works fine from a desktop, but we weren't impressed with the Web interface on the phone itself.
