Problem:
This might help someone. An iPhone 4 with version 4.2.1 installed may crash repeatedly when opening the App store. It will show loading for a few sections then close.
Resolution:
Make sure the App store icon is on your home screen. Move it there temporarily if you have to. Reboot. Open the App store, if it crashes then double click home to close it. Reopen it, then as soon as you see the "loading" screen click the home button to close it. Then double click to see it running in the list of programs and launch it from there. It should work this time.
As a habit you might try close the App store on the "updates" option that way when launching it your not trying to load so much.
