"Apple estimates that 250,000 iPhones were sold with the intention of unlocking"
During their sales call, Apple stated that they estimate (and they have sales numbers minus AT&T numbers so they know that they are talking about) that 250,000 of the 1.4 million iPhone sold were unlocked.
That is over 17%!!!
Way more than almost anyone has anticipated.
Also, Apple is "estimating" when they have sales numbers and AT&T figures at their disposal. It is in Apple's financial interest to artificially deflate this number so they probably rounded down.
Just to clarify: this is sim unlocks which is much less than the number of people on AT&T who unlock their phone for just the applications. That is probably closer to 50%.
