iPhone only uses EDGE, not 3G, for internet, so that would limit its use
and attractiveness in most other places, like Europe for instance, where
users are used to the much higher speeds of 3G broadband, instead of just-
a-little-faster-than-dialup of EDGE. It'll work on the GSM as a sellphone,
but not on 3G as a high speed internet device...........yet.

That's why it doesn't sell well in European markets, cracked or
uncracked....besides being hobbled, of course, into a WebTV device.
