What is the storage of the iPhone?
4Gb and 8Gb and new 16GB
What will the iPhone be available on in the U.S. and Canada and other countries?
In the U.S., Apple currently has a "multi-year exclusive contract" with AT&T. Nothing is known for certain about other countries at this point. The iPhone is a GSM phone, so regardless of the carriers that Apple may choose to make it available to, it will only work with GSM carriers.
In Canada, it appears the carrier will be Rogers. Since Rogers is the only national GSM provider in Canada (Fido is just another Rogers brand), this is to be expected.
In Europe, recent reports have indicated that Vodafone and/or T-Mobile may be potential carriers for the iPhone.
What technology does the iPhone use?
Old ones are Quad-Band GSM "Worldphone", and new ones are 3G.
Will there be an unlocked version of the iPhone?
Although this is not known for certain, it would seem unlikely at this point, due to the Apple's agreement to sell the phone exclusively through AT&T. It is expected that similar agreements may be put in place in other countries as well.
Can iPhone battery be replaced?
No.
Can the iPhone use a SIM card?
Yes. The SIM card slot is located in the top of the device. The SIM card itself is stored in a tray, and can be removed using a paperclip.
