I hope this is not way too inappropriate for our forum lobby, but I am looking for a used iPhone 3GS for development purposes.
Any suggestions where to get one, or does anyone here have or know someone who wants to sell theirs?
Last time(1 month ago) I asked about the price of a new Iphone 3GS it was around $650 or $700 at a place in Hamra, I dont remember the name of the shop though. Thats all I know :)

I assume that you want to start developing iPhone Applications.
You can do that on the iPhone Simulator which can be installed with XCode on a Mac. I currently develop iPhone apps this way. It totally simulates the iPhone and i never had a compatibility issues :)

PM me for details
The problem for me is that I intend to develop OpenGL ES games. Additionally I don't have a Mac, instead I have a half working hackintosh (without sound or hardware accelerated graphics). I still need to get the Xcode and iPhone SDK, but I am sure the simulator will not simulate OpenGL without hardware acceleration.
I will end up ordering an iPod Touch third generation for its low cost, and support for OGLES2. The things I will be losing however are immense (GPS and Bluetooth among other features..)
