If you value saving battery power like I do, then this App/Tweak is for you.

Now this is going to be a small, yet RAVE review about a nifty little tweak that has recently hit the Cydia store – “Auto3G’. This app is designed to save you TONS of battery life on your iDevice. What it does, is utilizes your “use time” by disabling the 3G service every time that you lock your iDevice. While it is locked, you simply won’t be running the 3G service. When you unlock, like magic, your 3G service is turned back on, and it’s restored. Now, most people won’t think that this tweak will do very much, but I can personally attest to the fact that this damned thing DOES work. I’ve been using it for approximately 3 days now, and while I have not observed the “100% extra battery life” it claims, I WOULD go on and safely say that I would estimate that it has given me approximately half (50%) more battery life than before. Then again, I always have my screen brightness set to exactly 50% anyway, so I am sure that helps as well. Regardless, I highly recommend this little tweak. You can find it in the Cydia store for $5.99. The price is a little bit steep, especially for such a tweak, however, it does work, and I am witness to that. Give it a shot, and tell us what you think!
