It looks like the community jumped the gun a bit when it was discovered that the
Ice Cream Sandwich update was waiting in Kies the
Samsung Galaxy S II for AT&T. It was there, for a brief amount of time. After a large number of people jumped in and made the update AT&T pulled it from the system stating it was merely a test. Those of you that managed to sneak in and snag it have nothing to fear, you should be running the version they plan to officially release tomorrow.
Many of you that were excited to finally get the update probably already installed Kies and tried to get it. If not, then you might want to get it installed now, just head over to Samsung.com and pick it up. The app is available for Macs and Windows PCs. This is important to know because AT&T has no intention of releasing the update via an OTA of any sorts.
