So ya I was wondering because I do eventually plan to go to 1.1.3 for the new google maps but how much space does each firmware upgrade take up as I know that there is only 300mb of space of the os partition of the iphone.

bosstools managed to free up about 10mb of space from ringtones and wallpapers.

I don't really think linking apps is such a good thing at the moment because of the issue with updating the app it's a headache.....
But ya any thoughts would be appreciated.
