Tonight Motorola started sending out emails to Atrix 4G owners that are members of the Motorola Feedback Network and signed up to soak test the devices. The soak testers will be receiving the updates to their Atrix 4G’s tomorrow morning 10am Pacific Standard Time. Judging by the email that was forwarded to us this update could be anything although we suspect it will be the 4.5.141 software update that we talked about the other day.

Tomorrow after 12 Central/10 Pacific you will receive a pop-up message on your phone that will mark the beginning of the software pre-release test. This email contains several links to a private area where you should provide your feedback about the update process itself and your experiences post-update.

We would be glad to see an Android 4.0 Ice Cream Sandwich update but figure it would have been leaked by now. Our source will send us more information tomorrow after the update to let us know what we can expect and will keep you posted.
