Ok, perhaps not 'docks' yet these are viable stands. The one with the adjustable 'gooseneck' is from Wal*Mart in their car accessory section ($8). You can use a section cup only or, in my case due to wood desk, use the included 3M tape 'coaster' that then the suction cup attached to. You WILL have to remove the foam on the inside of the holding 'arms' to make the phone fit. Works great.
The other is a Samsung "Mobile Phone / MP3 Player Desktop Cradle" P/N:ET-CS01SBEGXAR (around $10). On the bottom of this cradle are places to run a cable as needed.
And yes, i know my phone needs cleaning
