I’m not a big ‘pimping’ kind of guy when it comes to my iphone. In fact, I tend to keep as many thing off it as I can in order to increase speed (I’m the same with my desktop/laptops). However, when I saw ‘Supreme Preferences’ in Cydia last night, I thought I would give it a try. Ho man, LOTS of options for tweaking your iphone UI. I especially like the fine brightness controls, SMS/MMS controls and extended ‘home’ options. I have only just started playing around with it, so I need to find when I can change the default font (it changes to ‘typewriter?’ when you install it. But I may leave it now that I’ve seen it a few times.
If you do not already have winter board, I think it will install it for you … and of course, this is jailbreak only.
