"Island" like app for iPhones?

Ideas? iPhone camera is much faster scanning for Shopkick, would be great if I can load multiple profiles on the one device.

doubt apple would allow anything like that.

Maybe with jailbreak. What are you trying to accomplish? What iPhone model and iOS version?

Example: 'Slices 2' by @subdiox: https://twitter.com/subdiox

Load 2 instances of Shopkick.

Depending on iPhone model and iOS version, it may be possible with jailbreak and 'Slices 2' app mentioned previously. There may be other similar apps as well. Not for the faint of heart. You'd likely have to bypass jailbreak detection as well.
