My Desire is the version 2.1, the newest version 2.2 is the very thing I am eager to get. here are som questions always cathing me out pretty badly, 1. Is a gold card ( partitioned SD card) required for upgrading? 2. Is rooting anything to do with upgrading to 2.2? 3. Is it possible for me to simply download 2.2 from HTC.com and install onto my Desire on my own without all things mentioned above? Could you please gimme an easy-to-understand answer as I am ignorant of tech things.
