Why is the 4.1 update over 500mb big??

Why is it bigger than the iOS itself (under 500MB)?? If its really just a change in formula and the reception display it shouldn't be bigger than a few MB and will it actually eat up 500MB on the phone once its been installed?

When you update, it does a complete install of the OS. It doesn't just add patches on. And iOS4 for iPhone 4 is > 500 MB.

4.1 contains more changes than just the reception bars. I guess you mean 4.0.1, which also contains more, but not a lot.
