There likely will be more, but HTC isn't committing yet. "We're continuing to assess our product portfolio, so stay tuned for more updates on device upgrades, timing, and other details about HTC and Ice Cream Sandwich," HTC said.
Android updates are a contentious matter. Google's new operating systems must filter through phone makers and mobile network operators before arriving in customers' hands, and that can be a long process even in the cases where it happens. Older Android phones can't handle new Android versions, and carriers that have customized the OS with their own features have to re-customize it for updates.
In a study of 18 Android phones, Michael Degusta found the Android phones lagged iPhone models in support for new versions of the operating system. Owners of even newer Android models aren't wrong to wonder if they'll see Ice Cream Sandwich on their phones.
