as it looks like there won't be an external sim slot, contrary to the announcement at macworld that the phone would have a sim slot at the top of the device. so you're stuck with one number?! is that steve job's way to bind you to certain phone operators, making it impossible to change sim cards? (as unblocking a blocked sim card is not a problem anymore ...) as i understand it will not be possible to open the device (no battery replacement once your battery runs out). any hints on that sim card?
