noob question here, i just got my 3gs, googled on how to close apps instead of just docking them, all said that just by pressing the home button for 4 seconds... but when i did that the voice command came out instead of closing the apps.. anyone know the exact way to shut em down completely?

thanks bro that was very the useful~

is there another way i can call without adding contact to favourite list?
cos now when i clicked a contact in the contact list it'll go to the contact profile instead of calling them

oh now i noes thanks monkey

everytime i call out to my fren using my i3gs, they complain about the voice is too soft and blur... anyone having this problem?

do a restoration on the phone...
if i'm not mistaken u download the firmware, possibly 3.1.2
after that, turn phone off and connect it to your comp and open up itunes
then press ur iphone power button and home button for quite sometime until the apple logo shows up and release the home button but keep pressing on the power button
itunes will detect your phone in restoration mode and you'll see the usb and itunes picture in your iphone
press shift and click on the restore button in your itunes and select the firmware that you have just downloaded and wait till everything installed and synced
hope this help, or you can google iphone restoration for clearer picture
