How about setting up email with hotmail - since it is not dependent on service. The email stays with you no matter what - does not care how many "internet providers" you go thru.
If you want the best free unlimited solution - goto your local libarary and setup camp there. It's free and you will be surrounded by all kinds of knowledge. If anything search out any LSR Related book while you are there.
I take it you dont have a laptop with wireless connection - you could goto any local hot spot and get free access. Shoot even McDonalds has it.
If that solution still doesn't work - then buy yourself a cheap wireless adapter and see you if have any neighbors that have a unsecured wireless network and just get access that way. Or offer your neighbor a 20 spot to use their wireless network.
For you people out there who want to cheap out - setup a comcast account with the 50 mb service - then setup 3 access points in your house with wireless 802.11N then ask your neighbors to chip in for blazing download speeds at 50 mb/sec (peak) - If access points are setup right you could get 10 houses easily that can have service for $5 or $10 each to cover the costs. - you idealy want to be the host of the service because you can hardwire to the modem and have the fastest service
