The latest rumors surrounding the Samsung Galaxy Nexus release date on Sprint, suggests that the phone will be launched on April 15.

Motorola has promised for months to update the balance of its 2011 and 2012 handset lineup to Ice Cream Sandwich, but has of yet failed to deliver any such updates except for on the Motorola Xoom tablet, which is a Google Experience and developer reference device.

Unofficial rumors are all we have, as Google has been dead silent on the Nexus S update situation.

The Galaxy Tab 10.1 has yet to be updated to the latest Android release, and in the case of the Nexus S, the previous flagship Google Experience handset, the Ice Cream Sandwich update was rolled out and then backed out due to technical problems, and owners have been waiting for months for it to resume again.

Heck, it’s jubilant enough to make any fan of firmware updates shout with glee.

With Sprint’s LTE network still in its infancy (the first Sprint LTE smartphone, the Samsung Galaxy Nexus, is yet to even release), Sprint would have the shortest straw as it was the last to LTE after Verizon and AT&T.

We’re reaching out for word on when (or if) we can expect the refresh to hit these handsets, but Mountain View’s lips are shut in the meantime.
