The HTC Rezound is one of the most underrated, yet capable smartphones in Verizon's lineup. It's sad that it has taken so long for Verizon to bring new updates for the former flagship. They do have a new update for the device. Sadly, it still isn't Jelly Bean, but it is a new version of ICS and includes Global Roaming Support as well as a number of other features. You can see the list of features from the pic above, and here is a VZW source link below.
Thanks for the tip, HowardZ!
