AT&T has quietly revised its data plans for iPhone users, allowing some to switch back to unlimited data. The move comes just weeks before the heralded Verizon iPhone launch, which many analysts believe will cause a great number of AT&T customers to jump ship.

Verizon announced that it would be offering an unlimited data plan for new iPhone users, something AT&T got rid of last summer. Now, AT&T has backtracked, allowing some users that previously had the unlimited plan to switch back if they so choose.

This policy does not cover new AT&T customers who never had an unlimited plan.

According to a report from The Associated Press, "AT&T spokesman Mark Siegel wouldn't confirm the option to return to an unlimited plan.

"We handle customers and their situations individually, and we're not going to discuss specifics," he said.

It is still unclear just how big the threat of a Verizon iPhone is to AT&T, but stories like this seem to indicate AT&T is feeling the pressure. It appears as though indicating that you are willing to move to Verizon might get you the option of unlimited data if you stay with AT&T. I must say, it's nice to see consumers get a little leverage.
