iOS 4.3 - personal hotspot....

“AT&T plans to support the iOS 4.3 mobile hotspot feature when it’s released March 11,” the company told AppleInsider. “To utilize this feature, customers will need to subscribe to the DataPro 4GB/$45 tethering data plan.”

Which is really just confirmation of what we already learned after AT&T dropped its unlimited data plans last summer in favor of a tiered pricing structure. At the time, the carrier also announced that tethering would be available to customers pending an iOS update for an addition $20 per month. So to use the Personal Hotspot feature in iOs 4.3, customers will need the 4GB Data Pro plan ($25/month) plus tethering ($20/month). $45.
