    Hi,
    I see tuorial around using different APNs to enable/disable settings and I'm wondering what the APN really is.

    Is it a setting configuration for the iPhone ? Why there is a username/password ?

    Thanks,
    Tex

    APN = access point name
    Sometimes disabling an APN is useful if you roam into various networks that do not have unlimited access.

    It is a setting and I think you can reconfigure it using iPhone config utility.
    I would assume there is a username/password to ensure you don't accidently change things or use a network you should not be on ... but I could be wrong.

    Yes, it's a server that your phone has to log onto to perform specific tasks such as web-browsing, MMS etc.

    The server checks that you are entitled to the service, but it's not just by the username and password (hence the "open" nature of those), it's by your phone number and (I think) your IMEI.

    i.e. is this phone subscribed for web browsing? No? "You are not subscribed to a cellular data service", and so on.

    The thethering option wasn't visible in my (German) iPhone when I bought it . I found a site where I could download a APN config that enables it. So how can this "hack" work if the "is allowes for tethering" is server side ?

    Hmm, I have not researched tethering in detail as I don't do it. But I believe tethering is a use of the cellular data service. So you need to have a cellular data APN. You might get excessive usage charges but otherwise they use the same service.
