My 7-month-old iPhone 4 has some Problems and I want to find out whether it is a software or a hardware problem. Maybe you guys can help me Everyone of you knows the sound, when you hold your iPhone near (older) speakers and a phone call/text msg arrives or if there is data transfer. All WITHOUT 3G/Wifi. Now comes the weird part. Since yesterday i have these exact sounds over my iPhone speaker(s). Both the speaker on the bottom and the speaker on your ear while making a phone call (with EDGE) which is very disturbing while talking. Also i get these sounds over the bottom loudspeaker while surfing in safari (-> data transfer over EDGE). All of this only appers when i have no 3G/Wifi connection. So... is this a hardware, software or maybe carrier problem? I never had these problems in the last 7 months. I called Apple, but he didn't know about that problem and told me to find out myself if it is a software or hardware problem and if it's a hardware one to call them again.
