iPod Touch – Using as an External Disk

Maybe Linux on the iPhone, or since your question asked for "interesting" and not for "useful", Windows 95 on iPhone:

Give a guy an iPhone, a jailbreak, and an open-source, cross-platform x86 emulator, and it's just a matter of time before hilarity ensues.

Since it’s practically impossible to diagnose a problem like this without physical access to the iPod and the SoundDock, I’m going to give you a few ideas of what I’d try to do:

• If you have access to another iPod, try that of course, if that works, we’ve found a problem with your particular iPod.
• If you have access to another SoundDock… well, put your iPod in those and see if the problem lies in your SoundDock.
• Since the last two were two obvious (and you probably thought about them), let me tell you that you can go to an Apple Store with both devices and try the above combinations there. I’m sure that you will find another SoundDock in an Apple Store to try your iPod and that they also have iPods so you can try your Sound Dock. It doesn’t hurt to ask.
• In any case, the remaining obvious alternative is to restore the iPod, either to factory settings (and later using a backup) or to restore a backup (so you don’t lose everything).
• The final idea, is to try 4.2, but that should be the last step. You don’t want 4.2 to introduce new “undiscovered” problems on top of your old problem.

Sadly, there isn’t much else we can do from here. The can’t charge or incompatible device message is “ok” most of the time (I had that problem too with a car adapter), but it worked anyway.

I’m sorry I can’t come up with a better idea.

Just had this same problem... I fixed it by spraying a Contact Cleaner on my Ipod/ITouch.. and it works after... sometimes, Dust or Dirt will cause bad connection between the Unit and the Sound Dock Port *
