Analysts from investment bank Piper Jaffray are making some news today after releasing a report claiming that 10% of iPhones are actually being sold to groups that are unlocking them and reselling them. They seem to be basing this on the fact that there are a bunch of folks going in and buying the maximum single allotment of 5 iPhones at a time. If this is true, the actual number of unlocked iPhones could actually be significantly higher, as many unlockers are buying the phone and unlocking it themselves. On the flip side, there could be other explanations for people buying 5 iPhones rather than to resell them unlocked. Either way, it should be clear that there’s a fair amount of demand for unlocked iPhones, which again raises the question of why Steve Jobs ever agreed to an exclusive with AT&T.
