Every time I've used a 2.0, 2.1, or 2.2 jailbreak (iPT gen 1, iPhone, iPhone 3G) the entire device slows down. A fresh jailbreak (as in no apps installed) makes everything 10x slower. I tried restoring, then straight after restoring going to jailbreak, and everything slows down. Cydia takes 1 min. 45 sec. (Oh yes, I timed it on every device and averaged it) to start up, and another 30 sec. to refresh sources. Settings takes 20 more seconds to load than it did non-jb'd. Everything is slower. I love jb, but it's sooooo slow! Anybody else have this?
