    I just noticed that my iPhone 4S is listening on port 8021. I was able to see this using the free app Netstat from the App Store.

    Does anyone know what this port is used for?

    Would anyone like to check their phone and see if they have the same port open too?

    The port looks to be registered to Intuit but I don't have any of their apps!

    I'm curious......

    Localhost. It's just your iPhone (not connecting to anything).

    Did some googling around and yeah it's registered to Intuit for the purposes of "Intuit Entitlement Client". Googling for that in the context of iPhone and iOS reveals nothing useful.

    Wouldn't worry since it's listening on localhost.

    Found this http://openbsd.groupbsd.org/faq/pf/ftp.html

    I got the same open port with the "Fing" app...besides Netstat. (localhost)

    I've repeatedly read that there is no problem as long it's from localhost...but is by any chance a sort of "override" posibility using this port?
    Thanks for any comment

    it's some 'ftp-proxy' spawned by launchproxy...

    _ftp 26630 1 26630 842d2888 0 Ss ?? 0:00.02 /usr/libexec/launchproxy ftp-proxy -p -n -V -D3 -u _ftp -t1800

    you can disabled it: mv /System/Library/LaunchDaemons/ftp-proxy.plist ~
    and reboot
