iPhone 4 slow down?

[newiphoneuser]

Ive had this phone since about August. When I first got it it was blazing fast. Recently I realized it feels a bit slower. I have 4.2.1 jailbroken unteathered. I dont know if I should restore and rejailbreak or if its only that the novelty of it being new faded now that its been a few months and its just perceived slowness. Opinions?

I believe it's the jailbreak bro, they claim jb doesn't slow down the phone, but for some reason my iPhone 4 jb on iOS 4.2.1 slowed down my phone after a few weeks, I restored and removed the jailbreak, better off updating to 4.3.1 and jailbreaking that through redsnow, I've never had speed issues with jailbreaking except for 4.2.1.
