I understand that the message alert tone not playing is a bug of the 3GS which I get every now and then. However, I have another bug whereby when someone calls me, the slide to answer button is completely none responsive. I have to double tap the home button to call up the iPod play controls, and then the slide to answer works. This doesn't always happen, but does at times and it's very frustrating trying to catch the call before it goes to voicemail! Another bug I have is with turning the device off. I press and hold the power button, and slide to turn off. The spinning circle shows, and then the screen goes blank. However, instead of remaining off, the lock code keypad reappears on the screen, and the phone starts to reconnect to the network (searching...). Then after a few seconds more, the phone finally switches off completely. Again, this only happens intermittently. Does anyone have either of these 2 extra bugs that I've got? Michael.
