Interesting changes, but if it is anything like the mini-uicc which in some countries, notably Australia, where some operators glued the mini-uicc in place to prevent subscribers taking it out of the handset, then this new 4FF could be targetted for the same treatment. Given its size, I get the impression that the original idea and concept associated with digital mobile communications of migration to innovation technology are being made slightly harder. I have made reference in my blog to the size factor, but to be clear we are talking about the size of a 4FF uicc that can be compared to the size of an eye contact lense.
