After living with the slowdown caused by winterboard for months, I've finally uninstalled it. I tried to convince myself it wasn't there for as long as I could but every single app was affected. Launching apps, typing, etc. was all noticeably slower. So far I haven't found a reliable way to replace AppStore puchased icons so I guess I'll be sticking with the default icons. I still have categories, a custom dock, custom keyboard sounds and sms bubbles. Anyone else ditched winterboard in favor of a "it just works" iPhone? P.S. Anyone who says winterboard doesn't slow you down is lying to themselves.
