It was only last week that Sony began to update the Xperia P with Ice Cream Sandwich, but it looks like the company is now going full steam ahead and bringing the update to no fewer than 8 more devices this week.
A post on the Sony Xperia Product Blog this morning said that the update will be coming to the arc, arc S, neo, neo V, mini, pro, active, and ray "starting from this week". Depending on the country that you live in, you may have to wait a little longer for the update, as it will have to be approved by local carriers before it's rolled out.
If your phone hasn't been updated to Ice Cream Sandwich yet, don't worry; Sony plans to rollout the software more of its devices in the coming weeks, saying:
Xperia mini pro, Xperia neo L and Live with Walkman are next up, and will start to receive their serving over the next few weeks.
Users currently running Gingerbread will have to use Sony's PC companion software to upgrade their phones, but if you're already running an earlier version of Ice Cream Sandwich, you will be able to update your software over-the-air.
