"PocketMail is a service that lets you send and receive e-mail - and send
faxes, even - from any old voice phone. Mobile, landline, payphone, PABX,
it doesn't matter. All you need to access the service is a "PocketMail
Device", and I've checked out two - the Oregon Scientific PM-32, and the
BackFlip for Palm, that adds PocketMail features to various Palm organisers."
