Been there, done that. (Score 1)

A couple years ago when I did in-person tech support, the company I worked for paid for an alphanumeric pager with unlimited messaging. The company that provided the paging service had a web page that you could enter messages into, but charged extra for an email address to send messages to. I set up a sendmail alias to use a quick & dirty perl script I wrote to submit messages via the POST method to the page's target cgi script, and bam, nearly instantaneous email on a $20/mo pager (that I wasn't paying for :). Adding fetchmail to the mix let me get all of my email on it, if I wanted... but I found that got annoying. Of course I couldn't reply to messages on the pager, but composing messages on any handheld or smaller device is painfully pointless anyway, IMHO.

I've tried doing something similar with my fancy-schmancy PCS phone, but it cuts off messages at a uselessly short 100 characters, there are often long messaging delays, and the display is 12 columns by 4 rows.
