Wouldn't be so bad then to get the $5 plan and pay overage if it's only .05/message. Maybe even the .10/per message.
Trying to justify paying an extra $25/month ($10/date and $15/unlimited text) just for the 3G...I've got GPS in the car so that really isn't a big plus for me.
I called AT&T. The rep I spoke with said with an iPhone TEXT MESSAGE plan, the OVERAGE cost would be .10/text which could save some people from having to get the UNLIMITED if you wanted to save a few bucks somewhere.
Just FYI...
