I had been using the old MediaWorks plan, which was $19.99/mo for something like 5000 text messages, 200 MMS, and unlimited MediaNet (internet). A while ago (10 months?) they changed the MediaWorks, chopping the MediaNet down to 2mb but keeping the price the same (go figure). This year, I'll have to go with the $24.99/mo unlimited MediaNet (internet)... That package is designed for internet that you attain using your phone... There is a $44.99/mo (or something like that) for unlimited PDA MediaNet, and the $79.99/mo (promo now $59.99/mo) for DataConnect, Cingular's data plan intended for laptop usage. As others have found out, you can 'tether' your phone to your laptop, and use your laptop to get internet data THROUGH the phone. This means that Cingular won't force you into the God-awfully-high-priced DataConnect package... Of course, there's always the disclaimer that they MAY see this and charge you PPU (pay-per-use, which you do NOT want to have if you rack up the mb's). However, between what I've heard and what I've read on Howardforums, nobody has ever had this happen to them. In the cases where folks do have monstrously high bills (>$500 for data alone), it's because the Cingular rep did not remove the PPU feature when they activated unlimited ($24.99/mo) MediaNet. Of course, you do not want to tell the Cingular rep that you will be tethering, since there's a good change that they will NOT put the unlimited MediaNet package on the plan and force you to go for the higher-priced plan.
