HTC has been promising Ice Cream Sandwich to Rezound owners for a while, and now it looks like they are finally going to deliver. HTC confirmed in an email sent by their customer support that Android 4.0 would start to arrive on the Rezound later this month. HTC stated "The ICS (Android 4.0) update will be released for the Rezound by the end of this month (July) with final pushes in August". It's good to finally have an expected release for the update, so cross your fingers that it doesn't get delayed. Unfortunately, no information was given regarding 4.1 Jelly Bean on the Rezound, and no specific dates were given on when we can expect 4.0 to start rolling out, but we'll keep you updated so check back.
