I have a UK purchased iPhone week 43 1.1.2 OTB with 04.02.13_g = 4.6 bootloader.
This phone has been jailbroken using the method here: http://www.sixth-ave.com/iturbo.htm
The phone works perfectly with a UK o2 PAYG SIM. Now I want to use my phone in two different countries, UK and Greece. When in Greece I have a Greek Vodafone SIM I want to use so I have purchased an X-sim (Turbo SIM clone) and have installed iWorld on the phone in order for the Greek PAYG Vodafone SIM to work when I am in Greece.
Now that a software unlock has been released I am tempted to use the ZiPhone (Windows) method to unlock the phone but I have a couple of questions.
My unlock route would be as follows:
Update the phone with iTunes to official 1.1.3 then Jailbreak, activate and unlock using the ZiPhone method here: http://www.iclarified.com/entry/index.php?enid=667
With this method I get the benefits of the new features of 1.1.3 and I wont have to use the X-sim for the Greek PAYG card.
My questions are:
1 - Is the update method OK to be used on an iTunes upgraded phone?
2 - Will I have to install iWorld after the upgrade or does 1.1.3 contain a larger database of country codes?
3 - I have heard that iWorld does not work with 1.1.3 is this true?
If iWorld is not an option I can update the country codes using this method: http://www.iclarified.com/entry/index.php?enid=598
4 - Has anyone used the above method of adding unsupported country codes, and does it work well?
Advice on any or all of the above would be appreciated
