iPhone 3GS - Extra Info.

[The Maestro]

Been using it for a while and testing it, here are a couple things i noticed that you may not know.

-the speaker is 4-7 db. louder than the iPhone 3G
-i dont know for sure but im positive the louder speaker is a software adjustment in the firmware similar to the volume boosts we have been using from cydia
-there is a high freq. noise when you lock the phone (bug)
-when you record a video if you turn down the volume you will eliminate any "white noise" or "hissing" (bug) (hopefully apple will fix this and the lock bug in the next fw)
-the video is capable of 720p but locked to vga (battery preservation most likely)
-the cpu clocks over 600 mhz, i got readings over 700 mhz idk why apple would say that, or did they say that? idk who did
-the battery is about 5-10% better, even as you probably didnt notice such a small percentage my guess is the upgrade in cpu and ram balances it out

This is all i noticed not sure if these details were posted yet, feel free to add to this list.

I have heard some reports that the CPU stays at about 500-600 during normal/light use, then cranks itself up to almost 900 when in demand (games, video compressing)

I am not exactly certain this is a 3GS-only issue, but I never experienced it with my original iPhone or my old second-gen iPod touch: it may be very sensitive to dirty power, to a point where the touchscreen will behave erratically - jittering around and touching somewhere way off from where your finger was at.
