As customers shift their attention to Jelly Bean, the Samsung Galaxy Exhilarate, which was released on AT&T in June, has just received an unexpected cold dessert treat from AT&T and Samsung – something that even we thought won’t come this soon.

Starting today, you’ll be able to move your Galaxy Exhilarate up from Android 2.3 Gingerbread to Android 4.0 Ice Cream Sandwich. But because the ICS update won’t be rolled out over the air, you have to get your phone’s USB cable out and connect the device to the PC. Assuming you already have Kies installed, you should find the update waiting to be downloaded and installed.

The ICS update will bump up the eco-friendly phone’s baseband version to I577UCLH3 from I577UCLB8 or I577UCLD2. If you’re having trouble updating the phone and making the jump to ICS, you can refer to the following Galaxy Exhilarate support page on Samsung’s website.

Let us know how Ice Cream Sandwich runs on your AT&T’s Galaxy Exhilarate in the comments below. Are you hoping to see JB making it to your phone in the future?
