Android applications can be updated in 2 ways: the automatic way and the manual way.
- The automatic way is simple: as soon as Google detects an update of an application of Google Play Store (formerly the Android Market), it puts the application to update using either wifi or 3G.
- The manual way, it is simply that it notifies you when he discovered an up-to-day, free to you to apply the update or not.
3G, it is well, but depending on the country, it can be very expensive couter, either have a volume of data limited and sometimes even the 2 at the same time! Moreover, some large applications to do update via wifi so you avoid ruining you in data 3G!
