I was at the mall today and saw crowds around the cell phone kiosks, after investigating, tmobile was the reason for that. These plans are really tempting. I think the 2.99 nights option was probably something they either put on their site as a mistake or had it up briefly and took it down. if you follow Rolltide's link and click on one of hte other options on the left, you'll notice that the unlimited nights dissapears from the menu... too bad it's not available now, maybe they're planning on offering it later?
