I have an iPhone 3GS and I have heard that jailbreaking slows it down and such. However, I need the jailbreak because I use several apps such as Winterboard, not for themes, but for just a different slider and the "User Wallpaper" function. (Not using unlock btw) Anyway, I wanted to know if things like CyDelete are significantly slowing down/eating up my battery? I use the Winterboard for the User Wallpaper and the SBSettings. I will keep Winterboard even if it slows it down, but I would consider removing SBSettings and CyDelete if they make a big impact. Do they? Thanks *By the way, after a respring/reboot, I usually have 160MB of free RAM.
