iPhone error message

[DwinHell]

I am using iPhone 2g which is being gifted to me by my cousin on my birthday , everything is workign fine but from few days i am getting constant message as This accessory was not made to work with iPhone. When i had a checked for the same i found out that nothing is being plugged in. I tried redoing its firmware but this doesn't help. Can someone please guide is it an hardware or software error.

In that case i would suggest you to reset your iPhone and have a check for the same it might happen that by mistake you have enable any option because of which you are getting such kind of messages. If that also doesn't work then try to blowing some compressed air into the dock port and headphone port to loosen any dust that may have been the cause.

I have try to reset my iPhone and at the same time i have also try to blowing some compressed air into the dock port and then try to switch ON my iPhone but still getting the same error message. Does anyone know how to over come from this message, i have really got frustrated with this message from few days, at last i don't have any option apart from buying a new one.

I was also getting same error message, i took out the sim and put it back again and the message was being fixed, if you are still getting the same message then i would suggest you to take your iPhone to service center, it might happen that your dock has got damage because of which you are getting this message and if your iPhone is in warranty period then they will replace it at free of cost.
