"Accessory not supported by iPhone?"

Yeah I'll get that every now and the too with certain accessories. If you turn the screen off with the top on/off button and then plug it in, it usually works. Weird...

Clean the dock connecter with a cotton bud and try again.

The problem sounds software related. Have you considered restoring the phone to factory settings?

you have your blobs and APTicket saved for 5.01? if so you can restore with 5.01

did you try noaccsplash in cydia?

same thing with a jbl speaker dock

this is soooo annoying

i have the same thing
- iphone 4 latest os (nothing jailbroken or smth)
- jbl iphone dock with speakers (this round ufo saucer thingy (very standard jbl speaker dock))
jbl onstage micro i think

does not work anymore - accessory not supported - i mean - W . . . . T . . . . F !!
this is REALLY annoying

you buy apple because it just works
this kind of defeats the purpose of buying apple stuff

same here, "accessory not supported", will definitely switch to another company for my next phone.

Not Supported by this Iphone

I have an Iphone 4s running IOS 7.0.2! I bought two, not one but two, Ihome alarm clocks. I get the "This accessory not supported by this Iphone."

I thought the first ihome alarm clock was giving me this message because it wasn't compatible with the 4s. Nothing on the box said good for "Iphone 4s." It charged my iphone so i kept it using the phone alone to sound alarms. But it would not play music, or auto sync the time and date.

This second one I bought, the Ihome id45, clearly states on the box that it is made for the Iphone 4s. But alas, I get the same error message. The phone charges on the alarm clock, but the apps and music don't play through the alarm clock.

I have turned my 4s phone on and off, I have performed a soft reset, I have performed a hard reset. I have cleaned both the docking port and my cell phone port with a Qtip. Nothing.

So, I got my wife's phone, an Iphone 4 running IOS 6.1.3, and slipped it into the dock on the alarm clock. It works fine. All features are available.

Can anyone give me some advice on what to do now?

Hi guys!
I've got the same trouble, but there is one simple decision: if you have a plastic connector installed on your JBL OnStage, just throw it away and it works perfect!
I think it's just because the length of connector of JBL OnStage is not enough to make it work properly.
