We're working hard to provide current Android-powered phones with an upgrade to Froyo (Android 2.2). The Desire and Acclaim are targeted to upgrade later this month, but may be pushed to January due to technical issues we're resolving with HTC and Samsung. The Mesmerize and Apex will receive Froyo shortly after. We truly appreciate your patience, and we'll let you know the moment we have additional info!
