Can't get Safenote to open; freezes on loading screen I've had the Safenote app for quite a while now and have a lot of useful notes in there. But now it won't open—it's frozen on the loading screen. Is there any way of getting it working again?

I'm using an iPhone 4 running iOS 5.
If Lizzan's suggestion doesn't work try rebooting your phone by holding down the power button and sliding to power off. That can free up additional memory that may allow you to run it again.
