I have an iphone 3gs that I got about 10 months ago, it has been an amazing phone up until recently. It has it's occasional issues that pop up sporadically, but recently it has been a lot slower with download speed and overall internet/multimedia usage. I have speakers at the head of my bed and when my phone is locked it never causes distortion unless I receive a mms or a phone call, but when I unlock it near the speakers then it causes distortion (I do not have any incoming or outgoing data, I just unlock it) and the same situation happens for when I do lock it. I was wondering what might be wrong with it and any suggestions as to how to fix/replace my phone.
