Just got off the phone with ATT support in regards to the Tethering option for those of you thinking about it. You pay $25 for your current 2G data plan, and $45 if you switch to the 4G tethering plan. However.... You can switch back and forth between plans if you desire, and.... ...wait for it... They prorate. meaning that if you switched to a tethering plan on the 1st day of your billing cycle, and only needed it for a week, and switched back to normal data... Your monthly bill would be 7 days at $45 rate ($10.50) and 21 days at the $25 rate (17.50) so you'd essentially pay $2.50 for that week. If you buy the wifi IPAD, you have NO CHOICE but to pay for the data per month. Obviously if you travel a lot, or need the constant access in no wifi areas, then the tethering plan/3G makes the most sense, but if you are like me, and are only worried about the occasional trip, etc... The switch back and forth makes sense. Almost more so than Jailbreaking, especially if you take the double data into consideration.
