Yes, one can use iPhone in any country having a GSM network but the iPhone should have been bought without any ATT or TMobile plan lock in the first case. The other option is unlock the iPhone before using any GSM SIM in it (NB: Donot upgrade the iTunes or any iPhone system software after unlocking as it will lock it again, eg. new OS 3.1.3 or latest)

It depends if the original phone the SIM card belonged to was saving them to the SIM card itself. Here's some clarification: The SIM card will retain contacts from a previous phone. The iPhone will not recognize SIM contacts until they are imported to the Contact list via Settings > Mail, Contacts, Calendars > Import SIM Contacts The iPhone does not save contacts to the SIM card, and therefore if the SIM is from an old iPhone there won't be any SIM contacts present.
