Stang68,
Which data are you worried about? It might be easier if we start there.
There is an app that backs up all your text messages to the web. Your contacts will also be backed up to gmail. Any apps you paid for remain paid for. The majority of apps you have downloaded will automatically redownload to your phone again. You will have to set up your desktops again, placing icons where you want them.
As others have suggested, rooting is an option to grab all that data, then you can return the phone to stock condition and return it. You will need to root the new phone to get the data back. As you might suspect, returning that phone to stock will result in losing the data again, so you'd have to remain rooted.
NewDroidOrder...that would be insurance fraud. Please refrain from suggesting that, thanks.
