My 3G seems to be the same in terms of speed. iBooks has pretty lousy performance on it though.

The new mailboxes make it worth it for me.

Jailbroken? Don't enable wallpapers and multitasking. You'll find out why it isn't supported officially by Apple. Absolute shit performance if you do.

Yeah I upgraded mainly for the new Mail features (grouped conversations and archiving for gmail). The phone isn't jailbroken, but I'm going to try a full restore and see what happens.
