Yesterday, AT&T announced an unlimited voice plan for the iPhone that still comes with a paltry 200 text messages.
Now, we have word that AT&T will be jacking up the price of text
messages over your plan's limit to a whopping $0.20, with multimedia
messages going up to $0.30 (not that the iPhone can send those). If you
send lots of text messages you'd better sign up for a larger text plan
or risk adding some pretty crazy fees to your bill. [Broadband Reports]
