Best bet is to get a GSM cell phone IrDA capable and just choose whatever ISP you feel like. Use the infrared port for wireless connectivity. I use Earthlink as my ISP. You can get the PC Card cradle and Sierra Wireless PC Card modem, but that combo costs $400-500. Then you have to go through AT&T to get service and that costs $30-40 a month and that's provided you get a 1 yr contract. I forget all the details cuz I did it over 3 months ago.
