Am I imagining things, or, does installing (since removed) iFile seem to slow down the tweak? I had it on 2.0 for the longest time because anything faster seemed too fast for me.
I installed iFile to change an app icon and then I *THOUGHT* I noticed it slowed down, so I uninstalled iFile.
Now I'm at 3.3 and it seems to be the same speed 2.0 used to be. Maybe I'm losing my mind.
On another note, I uninstalled the hack just to test my phone, and I seriously can't believe how SLOW the phone is afterwards. I don't think I'll ever want to go back, so I hope this hack is updated to work on later iOS versions or I might cry.
I removed it and re-installed & never had problems with iFile. Are you on the latest version?
