Order an iPad 3G Before June 7 to Keep Unlimited AT&T Data Plan
People who purchase an iPad Wi-Fi + 3G model before AT&T removes its unlimited data plan get to keep the option of paying for unlimited data. However, the iPad is back-ordered nearly everywhere, making it impossible to receive a new iPad before the June 7 switchover. In response, AT&T has stated that people who order the iPad by 11:59 PM on June 6 will be grandfathered in, even if they don't have the iPad in hand to activate the account.
