I just got a Sprint HTC Evo 4G, and discovered it is running Android v2.3.5 (Gingerbread). I manually checked for updates, which downloaded the latest security patch for 2.3.5 Gingerbread, but did not update it to a newer major OS version.
I did some searching about updating it to a newer Android version, but most of the articles I found either have dead links or require climbing up a steep learning curve to root and then flash(?) the device.
Are there any methods for easily updating to (ideally) Ice Cream Sandwich, without needing to learn the software innards of my device?
