Just noticed more weird iPhone issues last night. Hit the Home button, it went to favourites in the phone app. Tried it again, same thing. I made double sure I was only tapping once and not twice, but I couldn't get out of the phone application. Ok, I'll just turn the phone off and on again. Pressed the 'Sleep/Wake' button. I didn't get the "Slide to power off" display, it just went to sleep. Tried several times, but no matter how long I held it down, it just went to sleep. Eventually, had to do a reset "Home-Sleep" which worked. Then tried an app to see if everything's ok (Papijump) and the graphics were weird. It was as if every second frame was offset by 30 or so pixels giving a really irritating flickering effect. Everything is ok now, but yikes. Every time I use my iP3G I get different issues.
