I've heard that there is no difference whatsoever from the phone and the service that is on the special business plan that is $15 more per month ($45 business plan vs. $30 "regular" plan) than there is from the basic.  They are not going to sell some phones with Active Sync and some without, so how will they know if you are using it or not to sync with Exchange?  College students may want to sync with Exchange, does that mean they will have to purchase the $45 business plan vs. the $30 plan?  You wouldn't think so.

Ray -- I hope you're right!  I called several AT&T stores this morning, and none of the sales reps had a confident answer.  Most, though, said they they believe syncing with Exchange will require the Enterprise plan.  According to them, the Consumer Plan is for syncing yahoo, gmail, and other web-based email accounts. ---Amy
