3G 4G Connection Speed Fix

Fix your 3G and 4G connection. Does your phone have problems switching from Wifi to 3G data connection? Check out this app.
Important: This app will only be effective if the manual (Flight mode) workaround described below successfully activates 3G data.
Details:
The simplest (manual) workaround for this issue is to turn on "Flight mode" and then turn it back off again when you notice no 3G data connection. This manual workaround is annoying, and if you forget to do it then you are without a data connection.
3G Connection Fix will attempt to activate 3G data by automatically toggling Flight mode on then off when the phone disconnects from Wifi, if the phone doesn't switch to 3G by itself.
This app will not work on Android 4.2 and above (for example Nexus 4) due to a change made in Android.
This app has been tested on:
Samsung Galaxy Ace (2.3.4 Gingerbread)
Samsung Galaxy Gio (2.2 Froyo)
