I am having some sort of weird springboard lag when switching between pages of apps. Well, it's not exactly lag ( my device is performing even BETTER after deleting LaunchDaemons) but more like a stutter whereas before the animation was completely smooth.
I know a MobileSubstrate extension is causing it because page switching is smooth when in safe mode. That shouldn't happen though because performance, battery, and RAM are not affected...
I am on an iPod touch 4G 5.0.1 Untethered with Corona & Redsn0w.
On my iPod, there's a little jumpiness but I wouldn't say lag. If you had tethered jailbreak, that was laggy. I only experience this "lag" when I have a ton of tweaks installed.
