"this accessory is not optimized for this iphone"

I know- this is total B.S.

My Iphone 3GS is flashing this message all of the time,

cuts out your sound, then you can plug in the headphone jack to speakers

then you get sound,but if you pull the plug you get no internal sound !

I can't even power down- THAT doesn't work !

I have anew app-

iQUIT !

Take the sims chip out and throw them all into the ocean.

I tried every fix described here, and nothing worked. I discovered a couple slightly bent pins. i took the tip of a sharp jacknife and pushed all the pins inward, cleaned the port with rubbing alcohol, let it dry for a couple hours, and pushed the charger in and out several times, and it did the trick.

Do at your own risk.

Also, there are small rubber inserts that you can buy to cover the port when not in use. They are $1-2 on the web. This will prevent the pins from getting bent again, or debris getting in the port.

Mikey has the right idea... A Lil blow of air in the dock connector and my vitamin world card did the trick along the pins is the fix to this problem- you will see the volume screen pop up and wala the phone is good as new! Guess from putting it in your pocket and all the debris that collects inside the port as well as plugging n unplugging different accessories could cause the damage a newbie can easily fix... One time using Mikeys way with my credit card and a Lil air had my phone up and running after hours of trying to fix the error without researching forever... I couldn't understand why but it was actually the easiest fix!! Thanks Mikey for your feedback' didn't want to waste a day at the apple store for them to do the same thing! Now my sound is uninterrupted and the phone is as good as new. I tried a hard reset which did " nothing " and like 5 other ways- Mikey is the man! Thanks again and good luck to all since it really is such an easy fix I don't see anyone running into any kinda problems. Be gentle when you slip in you card along the pins since I'd hate to see someone cause even more damage!! Good luck to all- Bware

Ive just had this exact problem!, and i fixed it by getting a dry toothbrush, and brushing the docking port, and suddenly, i havent got this message anymore, if you also use some alcohol, that can also speed up the cleaning of it!.

What the f*@!#! Is this a friggin Nintendo cartridge? If we're paying like $500 for a **** phone, is it too much to ask that a dock work properly? Seriously.
