Necessary for 3G phones ...

IMO, this is a required app for anyone with a 3G phone. 3G phones are susceptible to newer apps not shutting down properly, and to memory leaks, especially now that Apple no longer supports the 3.x OS and since Apple does not require backward compatability (Apple could learn a lot from Microsoft when it comes to showing that they value the relationship with their customers!).

This app allows me to see if my phones performance degredation is likely originating from an ill behaved app.

Ive used the app under iOS4 and under 3.1.3 The app does work better under iOS4.x, but that is moot for 3G owners who want their phones to work at any pace other than glacial.

I hope the developers tweak it a little more for use under 3.1.3, but even if they dont, I think that 3G owners will find it a helpful tool for extending the effective life of their phones.
