Slotmachine not working on safari mobile (4.0.1 ?)

[allfriendly]

The demo in the download package is not working in Safari. According to other messages, it should work with version 4.01. The demo package is using jquery.slotmachine.js and slotmachine.js in the dist folder, and both are 4.0.0. Is the package not updated, or am I doing something wrong?

Small edit:
Just found out that it is working on newer types of devices. It is not working on iPhone 5C and second generation iPad. Hmmm, is this a show stopper?
