    I'm trying to update my 9900 on o2 Ireland (it has been unlocked though) to OS Version OS 7.1.0.923 but it was released by DoCoMo. If I update it by doing this will my phone get locked to Telstra? Also, are there any good guides to help me update my phone step by step. The one offered by CrackBerry is quite outdated. Thanks

    If a phone is unlocked, it's unlocked for good. updating OSes has no effect on the unlocking of your phone so free to download and install any OS released for your phone after you've read the findings of its thread to see what others have experienced while using it

    Regarding how to upgrade, this forum is filled with hundreds of guides that ARE up to date. search and youll find it easily

    You have to delete the vendor.xml

    I would suggest you run a search for Elite1's guide to upgrading your OS. It's probably the best guide on Crackberry.
