This is why a Cell Phone should just be a damn cell phone and not some do-all do-hickey. My Cell phones (Work and personal) are the most basic models you can get, aside from the work phone also including the 'cell modem' option.

Cell phones are there to make calls, not to be a camera, a computer, a PDA or any other kind of device.

The more complex these things become the more issues like this will crop up and cause problems.

One more reason that cell phone manufacturers need to focus on the big three (battery life, signal strength, ease of use) instead of mindless feature-creep.
Most people buy bluetooth phones and don't know what to use it for, just that it's another thing they have. (I have a Bluetooth phone, but only because my Powerbook also has bluetooth and can sync wirelessly. Otherwise I keep it turned off.)

Most people really just want a phone that can hold contacts, get really great reception, and lasts a while between charges. (And, outside the US, send and recieve text messages easily.) Why not focus on these features? The same reason most car commercials are about performance and showing off instead of reliability and gas mileage; people are more convinced by flash than substance.

Repeat after me: Something that has a lot of functions doesn't do any of those things as well as a dedicated piece of equipment. (PCs are a special case; software isn't.) Just like the only unitasker in your kitchen should be a fire extinguisher, the only multitasker in your geek lair should be your PC.

I would love to see a simpler phone without features like Bluetooth. This would eliminate some of this out of the box. I may be in the minority, but all I need to do on my cell phone is make phone calls.
