Yesterday Shadez posted a thread on the possibility of ATT getting a RAZR device. Well after some "investigating", I didnt find much but I did find this article on Motorola's blog. It is an update log of what phones are on what Android OS. Before they list the devices and what OS they are currently on, there is a note from them about the ICS update
A note about Ice Cream Sandwich:
We are planning to upgrade DROID RAZR, Motorola RAZR, Motorola XOOM and DROID BIONIC by Motorola to Ice Cream Sandwich. We will provide more precise guidance on timing after post-public push of Ice Cream Sandwich by Google, as well as any possible additions to this list of devices.
Notice how there is not 1 but 2 RAZR's on there. There is the DROID RAZR and then the MOTOROLA RAZR. Now this may not mean anything at all. It can simply be a mistake on Motorola's behalf. But I thought it was a little weird having them list the RAZR twice with different brandings before them.
