While the rush for acquiring the latest 3G iPhone is on, there remains some lack of clarity about the data plans of AT&T. The carrier has not yet revealed any data plan inclusive of text messaging for the 3G iPhone that has unleashed a lot of confusion. Therefore, to resolve the error it might soon arrive with a new plan including MMS service for the iPhone 2.0 according to an AT&T employee memo. For the time being AT&T has a separate voice and data plan. The voice plan cost is in the range of $39.99 to $79.99 per month depending on the available minutes. Unlimited data plans will cost $30 for consumers and $45 for business users. As a result the cheapest monthly plan for an iPhone is $69.99.
