Android (rooted): Facebook's Chat Heads inspired the developers behind the popular Paranoid Android ROM to copy the system for a universal multitasking method called Halo. Now, it's available for download on Nexus devices.

We've talked before about the process of how Android updates actually reach your phone. A point update to the Samsung Galaxy Nexus from Vodafone reminds us why getting updates can take longer than you expect.

It's a low price on what's still a good Ice Cream Sandwich phone: Vodafone has the Galaxy Nexus in its online store for $29 a month on a 24-month contract, with no extra handset charges. There's also one month free, so the total cost of buying is $667.

One of the best things about the Samsung Galaxy Nexus is that it comes with a vanilla OS: no crapware and no bloated UI skin. But that doesn't mean that you also get updates directly from Google. If you bought your Galaxy Nexus from Telstra, Optus or Vodafone, you're not running the latest version of Ice Cream Sandwich, and you probably never will.

If you want a brand-new phone running Ice Cream Sandwich, then you can choose from a stack of carrier deals for the Galaxy Nexus. But if you picked up its predecessor, the Nexus S, during its brief period of availability from Vodafone earlier this year, you might also be in luck.
