My refurb iPad 2 has been acting up where the home button is flaky. Sometimes it works fine and sometimes not at all. I want to get it exchanged under warranty but don't want to go through the effort of un-jailbreaking, deleting all my data, etc. just to bring it to the Genius appointment and have it behave fine such that they don't exchange it. Does anyone have experience with demonstrating an issue with their iPad to a Genius on a jailbroken device?
