I'm very comfortable with Android root and modification but very new to iPhone jail break and modification. I jail broke my iPhone 4 ios 5.1.1 a couple of weeks ago and installed several apps and tweaks from Cydia. It's very different but so was Android when I started. I decided to try installing a theme 2 days ago but didn't like the ones in the Cydia store. After a Quick Google search "best iPhone themes" I chose "Leg1on HD". I found it at iThemesky.com, installed their app, & followed instructions to download and install the theme. Yes I read those. I know it's weird but that's just me. I tried to apply the the theme with Winterboard & nothing changed. So I thought maybe it just needs a respring. Still nothing. Ok maybe a reboot. Still nothing. Then I tried to open iFile to see if I could find the files & that's when I found that none of my Cydia apps would open. A quick look in settings found that all of their settings were gone. I've since found that iPhone Mail app and Safari will not work either. I've installed iSpirit on my desktop and browsed through the files on my phone and found that the apps are still there obviously they just won't launch. The icons are still on my screen but when I touch them they only blink like something is about to happen then nothing. My google searches have turned up similar problems but all are related to a failed jail break or a semi tether jail break issue. It's seems as if my jail break has come undone. I have iFaith and my blobs so I can restore and start over if I have to but if I don't have to that would be great. I'm open to all suggestions just keep in mind I'm still a noob. If I've posted in the wrong place I'm sorry but since my problem started with the theme this seemed the most likely place to start.
