I apologize if this post is crappy but I'm writing it from my iPhone.

I've been having a problem with apps crashing since my upgrade to ios 4. The official app store says the apps have been ios 4 tested so I'm not sure why they aren't working. I've been getting the latest version from **********. For example I got a game called gravity hook hd that worked before my upgrade to ios 4 but now it doesn't work ( crashes on load screen). Another app called itrophies is also crashing immediately after I click the icon. Does anyone else have this problem? Any solutions?

Again sorry for the simple post.
