I’ve also found a page, updated on June 25, dealing with apps that close unexpectedly due to memory problems. This is notable because one of the potential fixes entails opening iOS4’s tray of recent applications and closing them out manually. This level of micromanagement is one of my issues with iOS4 multitasking, though I’ve admittedly opened dozens of apps at a time without running out of memory.
If you’re fairly tech-savvy, however, much of the advice in Apple’s support pages will strike you as common sense. Fixing most problems typically starts with making sure the phone is up to date and checking that the thing you’re trying to do is compatible with your phone, operating system or wireless carrier. In many cases, restarting the phone is a suggested solution, and restoring from a backup is a last resort.
Still, if you’ve got iPhone problems, troubleshooting from the support pages is never a bad idea. At the very least, you’ll make some tech support guy’s life a little easier.
