The lawsuit was originally filed back in June of 2010 and accused both Apple and AT&T of touting unlimited data on the iPad 3G model upon launch, only to to have AT&T do away with unlimited data a few months after the iPad was released. The lawsuit claimed that affected users were victims of a "bait and switch" maneuver.
Now, a tad more than three years later, a settlement has been reached that will see Apple pay out $40 to every individual who purchased an iPad 3G model before June 7, 2010. Further, individuals who purchased an iPad 3G model but didn't sign up for a data plan will be eligible for a $20/month discount (for 12 months in duration) on AT&T's 5GB monthly plan.
The ruling will be finalized in February so eligible iPad owners will have to wait a few more months for their payout.
