2) Can the iPhone use a SIM card from another AT&T phone? If I am already an AT&T customer, can I just take the SIM card from my current phone, stick it in the iPhone and have it start working right away without having to give Apple my credit card number and sign up for an iTunes store account?

1) at&t has already said that the iPhone SIM will be specially provisioned (set up and identified in at&t's system) so that it *will not* allow you to use the iPhone data plan on *any other* phone on the at&t network. Your voice plan, however, will work on another phone.
2) You can put a T-Mobile SIM card (or any other SIM card for that matter) in the iPhone, however since the iPhone is *SIM-locked* (as most contract GSM phones from at&t and T-Mobile are), it can't *use* that card for service.








Here in Finland you can use the EDGE/3G-networks as much as you like for 10/month. Unlimited surfing that is. Dunno how much you are prepared to pay, but that's like 6x the price we pay here. :P I hope the phone will be unlocked here in europe, because those prices aren't that good at least not here.
