3G 4G Connection Speed Fix

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)

Comments and feedback suggest this app may also work on:
Samsung Galaxy Y, S, S2, Mini, Fit, Replenish, Transfix, Indulge, Pocket
Motorola Droid X
HTC One X, Evo 4G, Desire GSM (CyanogenMod 7.1)
LG C800G, Optimus One, P990, LGL45C, Optimus 4X HD P880
Experia U, X8, X10
