If you get a PDA mobile phone on a highspeed network and get unlimited data plan then you can use your mobile phone to access internet at DSL speeds via usb connection between computer and phone. I added unlimited data with sprint for $15 more a month. With couple bars of signal I got connected at over 500 kbps. Upload isn't as good though. I'm not sure how fast you need your connection to be so... might want to consider that.
