Motorola Droid Bionic users have been waiting for almost a year for Android 4.0 Ice Cream Sandwich and it looks like that time may have arrived. A select group of Motorola users are reported to have received invitations to take part in a soak test for the device and we assume this could be for Android 4.0.
A soak test is generally performed by Motorola on a small number of handsets, before the official release of the update. The soak tests are meant to ensure the update is fully ready for public consumption. In order to be eligible to partake in soak tests you have to own a Motorola device and be a part of the Motorola Feedback Network. The content of the soak tests are generally confidential and users are not allowed to share information about the ongoing tests with the public.
Considering the time it took Motorola to bring Android 4.0 to the Bionic, it is unlikely that the device will be upgraded to a newer version of the software.
