It was not that long ago TiPb passed along some warning signs we'd seen about AT&T cracking down on iPhone users who currently not on an iPhone data plan. Well they've gone and given all of you rebels out there one more warning for good measure.

After some digging around in AT&T's myWireless application, we have found yet another dose of legalese from AT&T that states they can and will change your data plan and charge you accordingly if you are currently using an iPhone with any data plan other than the iPhone data plan.

While this is nothing earth shattering, we figured we would pass it along so, if AT&T started following up on the warnings, our readers wouldn't be caught by surprise.

Switch to the appropriate data plan or possibly end up with a larger than normal bill?
