Hi Denise,
Jane's advice is correct. A SIM card (Subscriber Identity Module).
The SIM holds personal identity information, phone number.
Basically all the SIM does is carry your account information.
The iPhone 3G 3GS use SIM card iPhone 4 uses a Micro-SIM card.
SIM cards are used with carriers that operate on the Global System for Mobile
Communication (GSM)

Hi Denise
I have an iPhone 3G which is unlocked (originally locked to Optus) into
which i put a UK sim when travelling to the UK. All contacts apps etc remain
on the iPhone and are not connected with the sim card.
Your ihone backs up to iTines each time you sync with iTunes so all
setting/contacts/music etc remains intact.
I have PhoneView which i have used to retrieve sms text message from my
iPhone but it is not necessary to use it when swapping sim cards.
Unless I am missing something in your message, i don't think the US sim card
will be any different to using a UK sim card in an Australian un-locked
iPhone.
Have a good trip.

Hi All
I'm heading to USA next week and want to unlock my iphone 3 so that I can
put in a USA sim card. But I need to firstly download all my contacts, apps
etc (have already done the music) onto my
Mac. Then when phone is unlocked, I'll put it all back on.
Did a Google searcgh and one suggestion is to buy an app called PhoneView.
I've just tried the demo version and it seems to work OK but obviously the
demo version is limited.
It's only about $20 to buy - is this necessary or are there other apps that
are free?
TIA
