There are a few apps in cydia to zip/unzip, but most are terminal and the only one with a GUI you have to manually type the path where the file is and where you want it to unzip to. You might as well use the terminal if your going to do all that. There are also a few file browsers that zip/unzip in the appstore, but, They are very limited and a pain to make unzip something you downloaded from safari with the plugin. moving the file into the apps sandbox and then moving it back where you want it or modifying the app to brows out side its sandbox. Its all a big hassle. My idea is just give mobilefinder (the cydia version! Not the crappy appstore version!) the ability to zip/unzip. This would be very useful. No need to mess around in the terminal for something that should be a one/two tap job or spend hours moving crap or modifying some crap appstore app. Please someone make this! Or an app to zip/unzip that can brows, zip/unzip and move anything anywhere. The ability to do the same with .rar would be great to.
