I have tried about 5+ cables for my iPhone and have gotten mixed results here are my conclusions. This is the most up to date information I have , and will work for iPhone 2.1 and older.
There are three kind of cables that you can connect to the iPhone
Type 1
The first type Simply does not work, no video ouput and the cable will just say that the iPhone does not support the cable ( this refers to the headphone A/V cable and others of the like)
for example these will not work http://www.chinawholesalegift.com/p.../Ipod-cable/AV-Cable-For-ipod-16492542491.jpg
Type 2
The second type will play a movie for about 60-90 seconds, eventually it will stop sending the video out signal and tell you that the accessory is not supported. This is typical of the cheap av cables you can buy on eBay right now, and some of the older iPod dock connector cables. Basically any cable that does not SPECIFICALLY say "Made for iPhone 3g" will stop sending a signal after a while for example (I bought these and they did not work )

Type 3
The third type of cable works, and works most of the time but rarely it will decide not to send out a video signal. This is due to a loose connection . If you receive the " iphone does not support message" unplug and replug the cable and it should work.

These worked with My living room LCD, but failed to work on my indash 7" LCD
They do come with a USB cable end for charging which is a big plus
They cost 50 DOLLARS !!

Unfortunately these cables do not have the USB cable end for charging, but they cost only $40.
