I have a Palm IIIxe but do not own a modem.  Is there a piece of software (preferably freeware) available which will allow me to connect to a web-based email provider (like hotmail or Yahoo!) and download my email to my Palm?  It struck me that this function should be available, since this is very similar to what AvantGo does.  I synchronize my Palm every morning and each time I do, AvantGo uses my internet connection to put news content on my handheld.  Surely there must be some software which performs a similar function for email.  All the ones I've seen so far require a modem for connection.

Additionally, if there is more than one software solution for this, can anyone make a recommendation as to which would be the best one to use?

Thanks much.
