A few of you asked me to submit my review to Blues sticky so here it is... I put all the big points of the entire thread together into one easy to read post... Here... we... GO!
First: No sign of front camera, and unfortunately, no current sign of MMS. The sim ejector tool is made of metal.
Screen: Looks GREAT! I think it looks BETTER than the original. Very crisp, clean imagery. Doesn't seem to have the negative black issue. The touch sensitivity also seems quite a bit more responsive. The user interface seems faster with little to no lag when opening applications.
Audio: I wouldn't define the iPhone 3G as - Louder. However, it is certainly A LOT more clear. For phone calls it sounds better on both the earpiece and the speaker phone. Music sounds a bit more full. You unfortunately cannot change the sound prefs for mail, cal, etc.
Feel: Overall, it feels solid. Yes, the back is a finger print magnet, but what item in your arsenal that is a glossy finish isn't? Plus it easily wipes off The plastic doesn't feel cheap. However, the top button, vibrate switch and volume control seems A LITTLE on the chincy side but on the same token they feel like they are made from some kind of metal/plastic hybrid. I took a key to the back twice and gave it a few swipes back and forth each time and didnt see any visible marks.
GPS: It only took about 5 seconds to get a lock. It does not work without cell service because it needs that to download the maps. While walking it tracks your signal well. However, I was disappointed when I got in the car and took a drive as the blue dot stuttered along jumping to a new location every few seconds. I recommend turning GPS off when you arent using it to conserve battery life.
General Notes: The contacts app exists and is on the second page and I didn't see a way to hide it. As lame as it sounds the calculator is AWESOME! No landscape SMS. As expected the App Store was not functional at first try, but is apparently up now... There is no Flash Support yet. You cannot access iTunes over 3G, still only WiFi... I was hoping this would change so you can get any song you want on the go, maybe this will change. Beggars can't be choosers.
