Folks who need to have their iPhone’s unlocked, to use them on an unofficial carrier, know the nightmares of activation. If you accidentally update your iPhone to a new firmware, the iPhone becomes locked again. Unless you have an official SIM, you cannot activate the iPhone until new jailbreak tools come along to help you out. Your iPhone is then stuck at the activation screen, where all you can do is call 911, but I doubt they will help activate your iPhone.:p
Sherif Hashim, the hacker who found the exploit in the 05.12.01 baseband, has posted a new video showing that you don’tÂ necessarily need an “official” SIM to activate your iPhone. He discovered that you can use a “Phonebook SIM”, and iTunes will activate your iPhone. A phonebook SIM is a universal SIM used to transfer your phonebook from one phone to another, and works in all GSM phones. Apparently, this will work on iPhone 3G, iPhone 3GS, and iPhone 4, although you will have to trim the phonebook SIM to microSIM size, for iPhone 4. No jailbreaking or unlocking is required for this to work. Sherif used a Phonebook SIM from Dits, but, in theory, this should work with any Phonebook SIM.
Personally, I haven’t used one, and I’m not sure where to get one in Canada, but here’s what Sherif Hashim had to say on YouTube:
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
