I have an iphone 3GS. Over the last few days, I have been having trouble waking the phone from sleep. I have to push the home button for 3-4 seconds for the phone to wake up. When it does wake, there is a "play, forward and reverse" image with volume control displayed just beneath the clock. No music or sound is coming, just these images. Also, I can't seem to connect to my wi-fi. Also, the battery drains quickly--as if something is running in the background while the phone is sleeping. Once I do a quick reset, it seems to work okay--only to falter after a few minutes once again.
