The Iphone is not due out in Australia until sometime in 2008, but the hacker, who uploaded a video of the hack to YouTube, managed to place calls on the Telstra network. He was not able to receive phone calls, however, nor send or receive SMS messages. Although Telstra has an EDGE 2.5 network, internet access through EDGE was not possible either.
The video has subsequently been pulled from YouTube, but instructions and an account of what was and was not possible can be found over here.
The user, Ozbimmer, managed the crack by creating a custom sim card with a sim card reader and writer. Information from the AT&T and Telstra sims was combined to create the custom card that was able to allow calls out.
As he said on the forum, “this is not an unlock. The method only trick[s] the iphone [into thinking] that the genuine AT&T sim is used.” The method outlined by Ozbimmer is as follows;
1. Get the required hardware and software: (these are the ones I have used): An Infinity USB unlimited SIM reader/writer, a silvercard, SIM-EMU 6.01, and WoronScan 1.09
2. Get the IMSI, Ki of your carrier using WoronScan (I will call them IMSI-b, Ki-b)
3. Use SIM-EMU and create 2 files (1 Flash and 1 EEPROM) using the ICCID of the AT&T sim (ICCID-a), IMSI-b and Ki-b
4. Then use these 2 files to create a sim using the infinity usb unlimited reader/writer
5. Put this sim into a normal unlocked phone and make some calls/receive calls/data services
6. Then use SIM-EMU to change the IMSI of the original Flash file to IMSI of AT&T sim (IMSI-a)
7. Again write the silvercard with the new flash and eeprom files
8. Put this sim into the Iphone
9. Activate using the Cingular method as descirbe in Hacktheiphone.com
