The last time I tried cingular, they charged me $3.99 a month to enable data service so that I can use my phone as a modem. It uses the minutes and I can connect to a regular ISP like earthlink. The problem is the connection speed is SLOW as hell at 9.6kbps. I've switched to Sprint and use the Vision and am able to connect at 144kbps. The responds speed is still slow but once the pages started loading, its fast.
