since I installed the iOS4 on my device and the new XCode 3.2.3, my apps increased drastically in build size. Before my app was about 20 megs, now it's to 31 megs big - without any modifications to the game. That's a huge difference (and a problem, because of the size limit for cell carrier)!
Is it because of the 3.2 Base SDK (not 3.1.3 anymore)? Is there a way to find out, WHY it got this big?
