Hi guys, I googled a bit about updating to firmwire 2.2. I came across a topic on this forum saying HTC does no support hero beyong 2.1. However, I found some other links with a whole bunch of information on how to upgrdae anyway. I've never updated any firmwire, this is an old smartphone I received; so I was wondering if this is safe to do? Any input is helpfull, thanks in advance.
