How many mb/gb is the ios6 upgrade?

I want to upgrade my iphone 4s to ios6 it is now ios 5.1.1. My iphone is 16gb but now there's 7.5 gb available. I have this weird obsession over keeping lots of space free. How big is the ios 6 upgrade? And how long did it usually take to upgrade it. ( its really my first time upgrading) Thank you

It's 923mb ( to be exact)!

It is about 800Mb something.

I have an Ipod touch 4th Gen, and that was 512Mb, and that needed 2.4Gb free space, an it took roughly 5 hours to update (not connected to a pc and in an area of bad internet connection)

  • Should I upgrade my iphone to ios6? I just bought the iphone 4S. This is my first time ever owning an iphone and I'm trying to learn all the features. I keep getting a message to update to ios6 but I read some horrible reviews online. Has anyone upgraded yet and if so, have you noticed any problems. I'm hoping that Apple has fixed some of the bugs that came with the upgrade but I'm not sure. Any help or advice would be appreciated.
