What is the FHA Flip Rule?

A rule that prohibits the purchase of a property using FHA financing that has been recently sold in the past 90 days.

Appraisal came back over contract price, what does this mean?

The property's value is worth more than you are purchasing it for. Therefore, you have more equity in the house. In terms of the mortgage approval, it doesn't change anything. Mortgage lenders use the lower of the contract price or appraised value when calculating loan to value.
