Well if it is truly a 2G (Rev. 1) phone, then there is nothing stopping you from carefully downgrading to 1.1.4 OS to run this app. You can always restore back to 3.0.1 afterwards.
I have just installed iSIM 1.0.8 on my 3.0.1 iPhone, tried all the tricks i could find to convince a pre 2.x app to run. Nothing worked. :mad:
I assume you're trying to make it so you can use the SIM in another phone. Your best bet is either a direct transfer to the SIM using a SIM card writer, export your vcards from Addressbook to the phone via bluetooth, then save them to the SIM card (or not).
iFunbox is a good app for transferring contacts from your phone. I use this from a few days and it runs smooth in my phone. Make it a try.
You are better off distinguishing by features. The following links outline the differences between the three iPhone models feature wise. Main Page - The iPhone Wiki
Ifunbox is a free software from www.i-funbox.com
