Good news for Sony Ericsson owners, with the company confirming that a number of its smartphones will get an upgrade to Google Ice Cream Sandwich in the coming months.Yes, just like HTC, Samsung and LG, the company has announced the future arrival of the new operating system, but refused to give a timescale for it. According to Sony Ericsson: 'More detailed information regarding this upgrade, timing and global availability will be communicated in due course.'We wouldn't be surprised if it landed in the second quarter of 2012, which seems to be the expected date for all the other manufacturer upgrades. Although you'll probably want to factor in network testing and a gradual rollout to that. Let's say early summer to be on the safe side. If you haven't upgraded your phone before then.The mobile giant has given details of the phones getting the upgrade though, described as the 'Sony Ericsson 2011 Xperia portfolio'. That means the Xperia Arc and Arc S, Xperia Play, Xperia Neo and Neo V, Xperia Mini and Mini Pro, Xperia Pro, Xperia Active, Xperia Ray as well as the Sony Ericsson Live with Walkman. So a good number of phones, in all fairness.When those extra details are communicated, we'll let you know.
