This is my 3rd iphone from 2g to 3g to iP4. There have always been tweaks that Apple fixes with updates and I've come to live with that. But...I've had my iP4 for exactly one week and things are getting worse I run my own business and use my phone 4 hours a day. I have to use a bluetooth headset for both my own sanity and because my face constantly mutes and shuts off the iP4. I'm running 4.02 with a Plantronics 925. Everyone says I sound like I'm under water. I've unpaired, reset, and repeated no good. I know there's a noise cancellation issue but that's no excuse. As of yesterday there's a more than faint high pitched beeping during every call when I use the apple headphones. After practically being forced to upgrade because Apple conveniently made iOS4 not work well on 3g's I'm having worse issues with iP4. Don't get me wrong. I hate Microsoft. I Love Apple. I use Apple programs everyday to help me in business and can't imagine a life without them. That being said I spend $130 per month, $200 for upgrades every other year, and literally thousands per year on other Apple hardware and software for business and I cant use my BLUETOOTH? Can anyone help me with my sanity which is waning?
