To sync an iPhone and an iPad to the same MacBook-Pro I was able to retrieve the LPID from my iPhone and configure iTunes on the MBP to match (after corrupting the iTunes Library.itl file….. however I need a way to update or edit the LPID on the iPad to match the other devices; now using the iPhone LPID.

Any thoughts on editing the iPad LPID to match the MBP as described on this site? Should work but was curious if anyone has done this successfully.
