AT&T customers can now upgrade their Samsung Galaxy S2 to Android 4.0, Ice Cream Sandwich.
Samsung launched the update for the device earlier this week.
In order to upgrade the S2, AT&T users must visit Samsung's website from their computer and download the Samsung Kies Upgrade Program to their desktop or laptop.
Normally updates are issued OTA (over the air) with WiFi or data, however, ICS for the S2 can only be accessed and installed with the use of a computer.
The Samsung Kies Program is compatible with Windows XP, Vista, 7 and Mac OSX 10.5 to 10.7.
The upgrade is also only available for the SGH-I777 Galaxy S2 model, and not the SGH-I727 Galaxy S2 Skyrocket. It should roll out for the latter device in the coming weeks.
T-Mobile released the Android 4.0.3, update for the Galaxy S2 earlier this month.
This also is not an OTA update. Both Samsung and T-Mobile require users to upgrade by using Kies software and a computer.
Android 4.0, Ice Cream Sandwich launched on the Samsung Galaxy Nexus in Nov. of last year and is available on a slew of other devices including the new Galaxy S3, HTC One X, One V and One S.
The software introduced some new features to the Android platform including the improvement of the folders, contacts and widgets, along with a new graphics interface named Robato and the ability to use Panorama on the camera.
Google is expected to unveil Android 4.1, JellyBean at is Google I/O keynote.
The company created a giant statue of a glass spilling out jellybeans that it placed in front of the Googleplex in order build up anticipation for the software.
