Google made changes to Wallet so that it will run, but only on KitKat devices.

I believe this was to go around Verizon's blocking of Wallet in order to force ISIS on us.
Google Wallet works without a hitch.
Also i dont know if there is to much difference between ISIS and GW. but then again for some reason ISIS has never really worked for me.
Is there a big difference between wallet and isis?
