Well, we're getting there. A hacker named "ozbimmer" has managed to fool his iPhone into placing calls on the Australian Telstra telephone network, although he hasn't managed to receive calls as yet.

The hack was accomplished by modifying the iPhone's default SIM card to be recognized as an AT&T SIM, while actually containing data that allows it to be accepted by Telstra, TechGate reports. The hack requires the use of iActivator, which allows remote activation of the iPhone without connecting to AT&T.

Since a number of sources have already printed the hack, we'll give the first few steps to you too after the jump. Do we need to point out that this will void your warranty? OK, we will.

Here they are, verbatim. (The "I" refers to "ozbimmer"):

1. Get the required hardware and softwares: (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
