Gadget website Gizmodo, among others, has revealed and provided a download of what is apparently the first iPhone unlocking hack to be made available for free. This comes just days after iphonesimfree started offering a similar piece of software for $59.99 trough a number of resellers.

The commercial model Apple appears to have developed for the iPhone is that, in addition to the money it makes from the sales of the hardware, it also takes a percentage of the revenue its exclusive operator makes from contracts, call charges, etc.

If people are able to make any SIM card work in the iPhone then they are free to use whichever operator and contact they want, the vast majority of which would offer no kickback to Apple. Apple presumably won't be too happy about this development.
