There is a good news for the users of Samsung Galaxy S2 bought from AT&T. The news is that AT&T would be releasing the updated version of Android 2.3.5 Gingerbread for all such devices. Based upon the response and requirements of the customers, this software update would come with several enhancements. These improvements include improved WiFi calling facilities, improved battery life and certain enhancements in the caller ID. However, there is no compulsion in this update and if you want to stick with your previous version, you can choose to do so. If, however, you want to update your device to the next version you might have to wait for a while since it would take some time before the update is made available for all the devices. A slight problem that you would face with the update is that you would have to turn to Samsung Kies for this update and previously some users have complaints about Samsung Kies. However, the notification for the update would be soon available on your device and you can choose to update your device or can also decide to remain with the previous version.
