We’re now removing the fee to unlock your handset to give you the freedom to change the SIM in your iPhone™ when you travel overseas.
If you have purchased an iPhone™ 3G, iPhone™ 3GS or iPhone™ 4 from Telstra and would like to remove the network lock restriction, all you need to do is contact Telstra.
When you contact us, make sure you have your details: your mobile number, your iPhone™ serial number and your iPhone™ IMEI number. You can locate these by pressing the Settings app, scroll down and select General then press the About tab.
Applies to Pre Paid, Outright and iPhones on a contract.
+ve from me anthony!
But to Telstra: Should've been free from the get go! Shame on you Telstra but Kudos to anthony!!
Edit: Hence, this +ve is to Anthony (not so much telstra! :P)
