Nope iphone will not work in nepal right now coz its locked to work with cingular and yes it has a place to put a sim card. The iphone crackers are very close to unlocking the phone to work with other cell provider just watch out on the net. Just be careful if you find scripts like that and screw it up you may loose your warrant or just brick your phone. Just wait for gen 2 of iphone with 3G, EDGE is not worth the internet
