I did some searching, both here and on Google, but I haven't found a definitive answer, so I'm hoping someone can answer this question for me. It seems initially that FivelRows wasn't compatible with iOS4 (obviously, most tweaks weren't when it was initially released), but I'm wondering if it is now? I had it installed before on my 3GS running 3.1.3 and loved it and I noticed when I got Gridlock it mentioned it WAS compatible with, among other things, FivelRows, so I'm assuming it's working now? I know it seems like a dumb question, but I almost had a nightmare moment after installing SBSimplify last night (sent my 3GS iOS4 into a seemingly endless Safe Mode, which I've since uninstalled), so I'm a little gun-shy right now when it comes to installing apps and tweaks without doing my due diligence first. Thanks everyone.
