Updating iOS but not through iTunes?

[FortWorthMac]

Hey all,

I've got a friend I am going to meet ti help JB his phone. He currently has 4.3 installed so before the JB I need/want to get his phone current. My question is, is there a way to manually update the phone by having 4.3.2 downloaded before we meet? Tried to do it last night through iTunes at a Statbucks and the download was going to take over an hour on there network and neither of us wanted to wait that long.

Thanks
David

Google search for whichever ipsw you want. A number of websites post d/l links direct from apple's server.
You still have to install through iTunes. Press option plus restore to open the dialog box.
