Ok, first off, I love all the new features, but the trade off has not been worth it. I have expierienced these same bugs on both of my iPhone 3G's using 3.0 GM. I hope tomorrow's release improves it, but I doubt it. 1. Reception has been horribly worse since upgradeing to 3.0 GM. Same symptons on 2 iPhones. Dropping calls left and right, unable to hardly have a long phone call. Used to get 4-5 bars in my basement, now signal cuts in and out. Just aweful!! 2. Battery life is crap! Can barely make it through the day now vs easily going 2 days. That is with minimal use mind you. 3. This OS is not very stable. Web pages studder and hang, load much slower. Apps crash, I have had several times where all apps immediatley close right after opening, and than I do a hard reboot and it hangs at the white apple logo, have to hard reboot again, and it finally comes out of it. I have these symptons on both my phones, and one I did a full restore and it was no help. This is defintley the software, as before I had no issues like this. I expected much better than this for the GM, something tells me once this 3.0 goes mainstream and the masses start using it on their 3G's. I don't know how much better it will be on the 3G S, but this really is pissing me off!
