I know someone will correct me if i'm wrong but i believe the IPA file is a ZIP just with the extension changed.

If your looking to do a restore of the version that is currently on the phone i know in the past iTunes used to keep the file on your hard drive. If you have been doing OTA updates then as you can guess these will not be on your computer.

If your asking about iOS 6. It is still in GM release only so you will need a developer account.

Can you explain a bit more about what you are trying to achieve? I'm not sure I understand.

As noted above, the updates are already compressed. You're can't make them (much) smaller.

The update is mainly code. Code doesn't compress well. I bet Apple is interested in small updates as possible to save their own money distributing bytes. I doubt you will get anything smaller.

I think if you download iOS updates via iTunes, or web browser, it downloads the full install of that OS.
If you download from the iOS device itself, I believe it will download a delta update, i.e. an incremental update that is much smaller. Someone may know better than me however!

Cheers,
Joseph

Edit...

This site suggests the same thing "Note the ISPW files are significantly larger than the delta updates available through OTA software update, and are generally best used by advanced users."

The Game.

In the time you spent talking about it you could have had it downloaded by now.
