i heard from my friend that if you wan to really close an app entirely, you have to press home button for more than 5 seconds... but i did not test that though..

somehow is this after you upgrade to 2.0.1?
becoz mine is acting weird too although some crashes is common now.. :\

iphone2008, but does it show any indication the apps has been killed?

I thought the iPhone software closes the program whenever you press the Home key or other functions.
There's no background running support..
Is that wrong understanding?

RX330, you may be facing the phone's difficulties on latching onto a signal. When this happens, the antenna have its power boosted, resulting in a marked higher power consumption, to try and catch onto the 3G signal. This results in battery endurance reducing faster than normal, and the secondary effect of warming up your Aifontriji. Which in some extreme cases, results in burnt flesh if placed near your body.

My advice is to turn off 3G when you are not using it. I have resorted to that now, which in turn saw the signal bar returning to full bars, instead of 2, or even worse, 1 bar when 3G is turned on.

How about wanting to pinch in/pinch out on pics taken on a standard Nokia, only to realize it is only a crappy Nokia to begin with? I'm pinching air!

ohh.... the one where its only available in klang?
