why did my iphone quit working on Wadia idock?

I think you're a bit confused, Apple products work well for several years without issue. PC is guilty of guilty of your accusation, IME. I suspect user error, no offense.

Ejlif,

Before you reluctantly update.....at least unplug the Wadia, wait 30 secs, plug it back in and try docking your iPhone again. Start all over again from the unboxing.

As a matter of FACT: I bought a Cambridge iD100 dock over a year ago. I put an iPod Touch on it and it worked fine for a week or two then one day I get the same message as you did. I unplugged/replugged the Cambridge and it worked fine. It has now worked perfectly for over a year of non-stop use. I did not update or upgrade anything, just unplugged it.

Do you turn your phone off from time to time or do you just leave it in standby ? You should "reboot" it every once and awhile.

I agree that if it worked before it should work now. Things that go "bump in the night" are little spikes on the electrical line that you don't even know about but can create problems with the tiny microprocessors inside the Wadia... Could be you bent one of the 32 pins a little on the dock/phone connector a little when you re-docked it...have you put a new outer case on your phone?

Well like I said last time I updated my iPhone I lost all my notes in the iPhone which had some important things. I have not been able to find any copies of them on the computer. I thought all this stuff was just supposed to be handled you didn't have to have a computer science degree. I suppose I'll try an update and see if that helps the problem. I will also try the power off thing and see how that goes. If it were a pin on the dock problem I would not think my regular iPod or iPod nano would work and they do. Thanks for the suggestions.

You should definintely update your phone to iOS 6 regardless of the Wadia issue. I'm not sure what app you are using for notes, but mine always back up without issue.

Your problem might not be a pin on the dock. It could also be a pin on your phone, or some dirt or debris. Try cleaning out the connection on your phone. Also, does the phone work with any other dock accessories?

Think that's Apple's official new motto: "if it ain't broke -- quick, someone smash it. Smash."
