AT&T is starting to force capped iPhone tethering plans on people with unlimited data plans who have been tethering their devices via jailbreak, accounts suggest. The carrier has held a forced switch policy for some time, but is now allegedly giving people fixed deadlines, possibly with a hard cutoff of August 11th. Under AT&T's official data plans, tethering requires paying $45 a month, and limits total data usage to 4GB before overage rates apply.
