T-Mobile has just put up a support page indicating that the Samsung Galaxy S Blaze 4G (seriously, these names are getting to be a bit much) is going to be receiving an update to Android 4.0 Ice Cream Sandwich starting on October 3rd. The latest software -- version T769UVLF4 -- will bring all of the latest ICS features in addition to a Mobile Hotspot and Email fix. Unfortunately, it will only be available via Samsung Kies and not over the air like the previous update. That being said, we've got to be thankful that ICS is coming to the device via official means.
One interesting thing to note here is that T-Mobile specifically points out that the device cannot be rooted and receive the update. Of course most of us know this, but seeing it pointed out specifically in the support documentation is probably a good thing.
