How to Activate iPhone 4 without AT&T (micro) SIM Card?
This is a big question for people who bought their iPhone 4 from US Apple Store without having AT&T Micro SIM Card to activate iPhone 4, just like me.
If you don’t have official micro SIM card (AT&T), you can use phonebook SIM card instead.
I’m using DITS Phonebook SIM card
This is a normal SIM card, so I need to re-size it into micro sim card in order to be fit on iPhone 4 micro sim tray.
If you need a guide how to do it, read How To Convert a SIM to a MicroSIM with a Meat Cleaver!
Here are some images after re-sized. It’s a micro phonebook card now.

It’s fit on iPhone 4 micro sim tray.
I got my DITS sim card from local re-seller. You may get similar phonebook card like Rebel SIMcard, OneSimCard, or any other similar phonebook card. You may also try search phonebook card on eBay.
This card will be very useful to fix iPhone which stuck on “Slide for Emergency” and “Connect to iTunes” screen and/or fix The SIM card inserted in this iPhone does not appear to be supported on iTunes.
Once you’ve activated your iPhone, you can Jailbreak iPhone 4 and Unlock iPhone 4 baseband 01.59.00.
