I had a Samsung Instinct until I dropped it into a hole at the edge of the Earth. I didn't do too much research as I need a replacement stat. I picked up this HTC Hero from my Sprint store. For the most part it's been awesome. The envy of my friends, it did take a while to get used to it and honestly I'm still tweaking/optimizing it. I was having some battery issues and a few ass dials, so I installed the screen lock and my battery performance has increased substantially....I wonder if the phone wasn't just sitting idly on on my pocket draining the battery. Either way, I'm continually discovering new better ways to use this thing and am kind of obsessed with it. Great tool, great toy, and I really appreciate this forum; I found the answers to questions I haven't even asked myself yet.
