iPhone updates and required bandwidth

    Apple is ultra protective of their mobile stuff.  It¹s just going to get
worse in the attempts to circumvent the devices being ³Jailbroken².  Quite a
bit of behind the scenes checksums and re-checks going on.  They want to
make sure the device cleanly downloads, cleanly installs, and is not
tampered with. Itunes is responsible for doing all this in the background.

Subject: Re: iPhone updates and required bandwidth

sorry Joe if i wasn't clear,  what i was trying to say is I know there is a
solution to address the bandwidth issue caused by updates for OS X machines,
I am unsure if they have a similar solution for their hand held devices.
I am assuming they do or soon will.   I'm on the road right now,  when I
return to the office I'll take a look at the OS X update server and see if
there is any provisions for the iPhones and friends.

perhaps a squid caching server in-between the device network and internet?
back in the day this is how i mitigated other many to one client update

the OS X client machines poll/pull updates from the internal machine as opposed
to 100 of them pulling the same updates over the internet.  saves bucket loads
of bandwidth and  you can "pre ok" individual packages,  so the client just
updates without prompting.   I'm not sure but I suspect they might have
something which allows their other devices to poll this same source.  it would
seem reasonable anyway..
