All (or Mostly) Encompassing Mobile Device Emulator

My Google black belt has fallen off and I'm unable to find a single mobile device emulator that can be installed on Windows 7. I would be satisfied if it only supported iPhone and Android emulation.

Do any such emulators exist?

EDIT:

To clarify, I'm not asking if I can develop for the iPhone (or any other devices for that matter) on a Windows 7 machine. I'm asking if an emulator exists that would allow me to see a close approximation of how a site 开发者_开发知识库would be rendered on an iPhone, Android, or some other mobile device.

The Android SDK comes with an emulator, but to do iphone development, you will need a Mac. Bottom line.

Not exactly an emulator, but you can use a plugin for Firefox/Chrome called User Agent switcher, which allows you to easily render mobile sites using a standard browser.

• User Agent Switcher for Firefox
• User Agent Switcher for Chrome

You'll also need the actual user agents to switch to, I use the ones found on TechPatterns (below), but you can find many more lists just by searching.
