My ipod is well within the one year warranty but way over the first 90 days. My earbuds are shot and I heard about how Apple will replace them under warranty so I filled out the online form last week and received a replacement pair today. The thing is, there is a letter inside the package that says.... "If hardware repairs were not covered under the original Apple iPod One Year Limited Warranty or an Apple 90-day Service Limited Agreeement, an Invoice Receipt detailing your repair charges will be sent within five to seven days." So, should I open the foil package containing the earbuds or should I wait 5 to 7 days to see if I get billed? I would send them back if billed as the money would be better spents on a better pair of headphones. Anyone with experience with this?
