Your biggest obstacle at this point is finding a copy of update....
If you do find a copy and upload it then give it a couple of days before you start throwing in the towel and returning the phone bc mine took about 4 days for "something" to happen, so that my battery wouldn't get scorching hot and for it to last longer, and I haven't done anything to the phone once I upgraded to 2.2. I'm not a techy, but something was going on those 4 days that eventually worked itself out....
BTW I get about 15 hours on regular battery with moderate use (bluetooth always on, wifi always off, GPS off and on, and screen at 10% using a brightness widget), always checking email, looking at facebook/ hr, Pandora for about an hour/day, internet searches, and Bonsai 1hr/day.
