Today I did restore on to my phone. I have firmware 2.1 and I've used quickpwn 2.1. Everything was okay, but when I opened itunes I've gotten information that something filled 197 mb of memory. Itunes report that "other" is using 197 mb. I don't know what is "eating" 197 mb, so I thought, maybe jailbreaking is using this space. Is it true? Does quickpwn 2.1 while jailbreaking phone, writes some data which is later reported by itunes, like "other" and spending 197 mb of space?
