i am having a problem that is very troublesome. i got an iphone version 1.1.4, and out of nowhere, i get this pop up as soon as i put turn on my iphone, "This accessery is not made to work with iphone, would you like to turn on airplane mode to reduce audio interference? you will not be able to make or recieve calls." i press NO, and after that i have zero sound, as if the phone thinks that there is a device such as an FM transmitter plugged into it, witch i do not use. what i do use is a stupid adapter for my headset so that i can connect a tape tranmitter to the phone(man im ready to get the 3G) even so, i never get that pop up when i plug that stuff into it, only a FM trandmitter and i never use one. anyone know why this is happining? is there a fix? will i be satisfied by just upgrading to 2.0? SOMEONE HELP ME. THANKS IN ADVANCE.
