Well I looked up if any of the carriers had any deals. I already have a Verizon 2 GB data plan for my cell phone, so it looks like it would only cost an additional $10/month to add the iPad to that plan (am I right?). However, Sprint also has a pretty good deal strictly for iPads for 1 GB of data for $15/month. I don't have AT&T so I'd be paying the most for them.
If you are on Verizon already go with them again since you can setup a shared data plan plus their 4G is in like 500 cities when ATT is only in 65 or so.
