Hi,
I don't have a great solution here. Obviously you can print it out. A second (less elegant) solution is to use the "Save Report as CSV" command on the file menu to save it to a CSV file which can be opened by most spreadsheet programs on your computer or your phone.
Sorry I don't have a better solution yet - I'm looking at ways to save the shopping cart to the cloud so it can be more easily accessed from your phone.
