I experienced slow down with with iOS3, iOS4 has just continued the slowness. If anything it may have actually got slightly better. More than anything I think its probably just the age of the phone being around 2 years old. I've never really understood why computers get slower with age, even if there running the same os and you wipe them back like new, but I guess smartphones are going to be the same.
