Telstra at the moment charge if you want to unlock the phone from it's Telstra-locked network, most people are ok with this - but when purchasing a $1000 phone, you kind of want to own it and not be locked to just one carrier. Telstra have been charging customers a fee to unlock the phones.

All iPhones purchased from Telstra are locked to the Telstra mobile network by default and will only work with a Telstra sim card - even with this news, that will still be the case.

Telstra have had numerous customers ask them they'd like to use their iPhone overseas when travelling - by putting the local countries sim card in, but the network lock has prevented this from happening until now.

The removing fee has been removed, which gives customers the freedom to change the SIM when overseas. Telstra are confident you'll still remain a customer of theirs as they state their NextG network is much faster and you'll have a better experience on it.

To complete the unlock process you need to make sure you have the latest iTunes™ software on your computer. Once the unlocking has been processed, the next time you tether your iPhone™ to your computer, iTunes™ will unlock the phone.
