Hello! I've had my Desire over a month now, we've had some teething problems but this is the most consistent one - there's no call waiting notification on my phone. I've missed about 3 calls and several texts while in another call, but my phone doesn't give me any indication that there is something else going on. Some cursory googling found that other people have had their Desire make weird noises instead of a call waiting tone, but mine has nothing at all. Anyone have this happen to them or any ideas how to fix it? Although I'm fairly happy around technology I'm not too keen to root my phone, what with warranties and insurance and stuff. Thanks in advance!
