sigh.... ok, i guess i'll lead you a bit....
which carrier network has this esn in it's database? is an esn even assigned to the device yet (it's not listed on the paperwork)? maybe it's dynamically added to the handset or the carriers database when i select a carrier? if that's the case, might someone with some actually carrier or ios hacking background be able to use this mechanism to move phones between carriers by actually injecting in to the carrier databases?
i see a lot of implications here. the "duuuhhhhh, select your carrier" comments don't offer much in terms of anything.
