I finally found a work around and loaded three cartridges into my iPhone. The PiGo people suggested that one can download the cartridge to a computer (I have a Mac) and load the cartridge to the PiGo app via iTunes. After downloading the cartridges to my computer, I synced up my iPhone and checked out the contents of My phone. Under Apps, there is a section that lists apps that share files. After highlighting the PiGo app, you click "add", navigate to the cartridge you downloaded, and BINGO!

I'm a science teacher and I know that you can get a bag of 50 really strong surplus neodymium magnets for about 20 bucks through www.teachersource.com. They are ring magnets about the diameter of a dime.
