I just ran accross an app specificly for reading POP email on your cell phone:
I've been trying it for a day or so and it seems to work well. Typing is a bit clumsy, but you can have "canned" messages you can send at any time. I set one to tell people I got their email and to call my cell phone. The subscription is less than $3 a month, but like the web, it does use airtime.
It does seem more convenient than just using the webmail program on my server via my phone's browser. I, too, get a lot of spam, but you can delete messages from your phone without reading more than just the sender and subject. And will work with almost any POP account or Hotmail or the paid version of Yahoo.
Anyway, just something I stumbled on after I posted. Not perfect by any means, but it will work in a pinch, which is what I needed.
Setting up an email account specificly for the phone is a good idea, though! Thanks!
