    Hey everyone,
    Im using a curve 9380 running with OS 7.0.0. So i want to upgrade my os to OS7.1. but my mobile carrier is still not providing me the latest OS, they have only this OS7.0. My question is if i upgrade my os by other carrier which provide 7.1, will my phone lock to that particular network? Is there another way to upgrade my OS to OS7.1. Thanks

    I haven't had to unlock a phone before.

    I've had 3 or 4 OS's from all different countries & never had that problem.

    If you are going to update to another carriers OS make sure you read the link I posted.

    If you cannot find a second vendor file, download VENDELETE program. I don't have the link to that and don't use it either. I just search for the vendor files manually.

    Hey some people saying "Once it's unlocked, it stays unlocked."
    Is this true? Thanks for your help

    If you are talking about "unlocking to all carriers" for me I'd say yes.

    I haven't had to do that though as my bb has always been new & with their original carriers sims.

    May be someone with experience will confirm.

    Also we delete the vendor files so it doesn't have the carriers part within the OS.

    & no problem
