XSysinfo is a small utility that let you know more about your iPhone/iPod. Maybe this apps work better if I am using iPhone 😀
So far, what I got from this apps is what my iPod is using its memory for, but I am not so sure about freeing up memory part. Maybe someone can loan their iPhone to me?
Anyway put this apps on your watchlist, and when it is free again, download, install and try it out 😀
Here is some screenshots:
