AT&T has confirmed in a press email that it will offer its recently launched Mobile Hotspot service for the iPhone March 11th, the same day as the scheduled roll out for iOS 4.3. The offering will require a DataPro data plan at $25 with the additional $20 charge for tethering which allows for 4GB of data access per month, with the overage rate set at $10/GB. With the launch of the Mobile Hotspot service, the AT&T version of the iPhone 4 will fall inline in terms of features next to the CDMA version sold on Verizon, which launched with the capability and a slightly updated software version in 4.2.6.
