The manual says the standard $30 data plan is required. The only other option is a $45/month Enterprise Plan. No cheapy discounts.
Text messages are still $5, $15, and $20 for 200, 1500 and unlimited respective. (I think those prices are right.)
Early upgrades for original iPhone and AT&T customers apply too. AT&T is allowing one early upgrade per account per year. Just have to be forceful about it because at first they'll say 'No.' Be persistent and you'll get it.
I call BS, sorry 3 out of your only 4 posts to macrumors have been in this thread only!! And, no walmart "store" employees like yourself are covered by Apple's NDA, so I find it HIGHLY unlikely that you have access to information that has not been publicly announced by Apple....
On a different note, Apple may be adapting to the "new" economy of sorts....Wal-Mart looks to be one of the only retailers who will increase sales this holiday season....and it makes sense for Apple to want to take advantage of this. Yes, Apple computers will ALWAYS be a higher-end, premium, and more expensive product....but this doesn't mean Apple can't compete in the lower end with iPods and iPhones. Look at the iPod shuffle people!
