Sony is bringing Ice Cream Sandwich to the entire Xperia line

Ice Cream Sandwich, the newest (and arguably best) version of Android, will soon be available on the entire Xperia line of gadgets from Sony.

“We plan to upgrade the entire 2011 Xperia portfolio to … Ice Cream Sandwich,” wrote Sony employee Martina Johansson on the company blog this morning.

That portfolio includes such devices as the Xperia arc and arc S, Xperia PLAY, Xperia neo and neo V, Xperia mini and mini pro, Xperia pro, Xperia active, Xperia ray and Sony Ericsson Live with Walkman. All of these are smartphones, and some have special features for gaming, music or business.

“We are working on merging our current Xperia experience with the new features in Android 4.0,” Johansson continued.

Ice Cream Sandwich’s new features include a one-size-really-does-fit-all approach that makes the OS suitable for phones, tablets, TVs — just about any connected device, according to Google. Previously, Google had offered separate forks of the OS for different devices — the 2.X line was intended for smartphones, while the 3.X line (a.k.a. Honeycomb) was meant for tablets.

The new mobile OS version also features a ground-up redesign that places a large emphasis on user experience, large imagery and stunning typography. Google even built a brand new typeface just for Ice Cream Sandwich (type nerds can check out our deep-dive coverage, including type samples, for the typeface, Roboto).

What Sony hasn’t stated, however, is whether or when it’s bringing Ice Cream Sandwich to its tablets. The Sony Tablet S, which claims to feature “the latest version of Android,” is still running on the 3.X Honeycomb fork.

In fact, if recent reports are to be believed, Lenovo may actually bring the first Ice Cream Sandwich tablet to market later this year.
