Sherif Hashim has posted a video in which he demonstrates how simple it is to activate the iPhone 4, iPhone 3GS and iPhone 3G, without using the original SIM card that comes stocked. You can literally use any SIM card you want, however, you should keep in mind that any iPhone 4 users will be required to cut the SIM into a micro-SIM sized card.
Now before you get all excited, this does NOT mean the phone will be unlocked. This simply activates the iPhone. This is very similar to "hacktivating" the phone, much like we do when creating custom firmware packages. Without doing so, you're stuck on the emergency screen, essentially locking you out of the Phone for any use.
There is no programming needed, so almost anyone can do this without the technical knowledge that one might think would be required. While I don't fully understand how this works, this is what Sherif has to say:
instead of telling everyone who hasn't got the original sim that activation of the iphone is easy using a phonebook sim card, i made this video to show u all how it works , Use any phonebook sim card, they are there in radioshak, mobile phone shops or any mobile tech moles , any phone book simcard will do the trick, no need for programmable sims, all those phonebook sims used to save ur contacts and transfer them have a universal ICCIDs preprogrammed so they all work
To all those asking, I use this one Phone book Test card from DITS - Cdma Gsm Forum Mygsmindia. Yet, I used three other types and all work the same
