    Hello all -
    First post here.

    I have an older iPhone 3GS that I recently unlocked via AT&T since the phone's been out of contract for a while (I'm planning to switch over to AirVoice due to their much less expensive plans :D).

    In order to unlock the phone, as per AT&T instructions, I had to restore phone which also ends up doing an upgrade of the OS. I was previously on 5.1.1 and had no troubles but in order to unlock I had to update to 6.0.1. There was no way around it.

    Well, the phone unlocked fine, and the upgrade went smoothly, except now I'm having a very strange problem.

    My phone will display the message "Charging is not supported with this accessory" on screen background (e.g. not a notification - see the screen grab below) randomly. And this is when I HAVE NOTHING PLUGGED INTO THE CONNECTOR on the bottom of the phone. The phone is just sitting on my desk, not connected to anything, and when I press the button, it shows my wallpaper for a second and then immediately shows that error message.

    The phone charges just fine via iPhone charger plugged into wall, or iPhone cable plugged into computer.

    So far I've done the following, to no avail:
    1. Cleaned the tiny dustballs out of the connector port on the bottom of the iPhone - first using vaccum and then using a tiny isoprophyl alcohol swab.

    2. Updated OS to 6.1 (which came out like 2 days after I unlocked the phone).

    The phone seems to work completely fine otherwise. This is more of a nuisance than anything else.

    Anyone have any thoughts or things I might try? Just to reiterate, I believe this is somehow related to iOS update and/or restore as the issue was not happening until I did that restore/update.

    Thank you in advance!

    This is mostly always caused by a damaged flex cable. Usually brought on by water damage. Is the sticker under your charger port pink or red?

    First, you did have a choice, there was no need to restore to iOS6, it is the default action, but you don't have to.

    Second, I second that this message randomly appearing is usually caused by a damaged connector.

    Thank you both for your help!

    I just want to make sure I understand. When you refer to "flex cable" it sounds like you are referring to an internal cable within the iPhone rather than the external USB cable that connects to the dock connector. Is that correct?

    I'm sorry but could you be a little more specific about where to look for this sticker? I don't see any sort of sticker within the dock port and when I opened up the phone, all my numbered stickers are actually orange (I took a photo to show you). I don't see anything pink or red unless it is perhaps deeper within the iPhone.

    It sounds like you and the other responder are suggesting a hardware problem. Doesn't it seem odd that the problem would start happening as soon as I updated (and unlocked the phone)? It just seems odd to me that this would be a hardware problem as the phone never displayed this error until I updated the OS. :confused:
