@deejay1111, now I hate to bash an app, but why would you install an app to install apps when your phone can already do this on its own with out a third party app that doesnt offer any more advanced functionality then the package installer embedded in android. :s Besides, it looks like spyware to me. I see no reason the app needs access to location data or even internet access. I personally would remove it based on the permissions alone, never mind the fact it just wastes space. I looked at a few of that devs apps, and they all had the location based service permission, but why would an MP3 tagger need to know your location for example?
Requirements - Install Dropbox on your PC and your Phone.
Download the z4root.apk.
Place it in your dropbox folder on your pc.
Launch dropbox on your phone.
Download the apk to your phone.
Depending on what apps you have installed you may need to choose "package manager," otherwise it will go directly to a page asking you if you want to install it.
Click Install.
All done.
Now you can launch z4root from your app drawer.
