I recently tried a new application called Free Memory.  It does just what the name implies – it frees up memory on your Iphone.  Most applications want 20 MB free in order to run well.  Some apps even suggest you restart your Iphone before running their app!

Free memory will count up the amount of memory being used and give you a choice to free up memory – up to 20 MB.  I now do this before I run some of my slower running applications.  Performance really improves.  It’s the best .99 cent app I’ve purchased!  Give it a try!
