I've been building mobile websites this week, and needed to get some mobile emulators to test the websites on - mainly Blackberry, Android and iPhone emulators. I found a great (free!) iphone/ipad emulator called iBBDemo2 which you can download from here:

http://code.google.com/p/ibbdemo2/

This program simulates an iphone and an ipad in one go. Install and Run the program then press ctrl+1 to display your webpage as ipad, or ctrl+2 to display as iphone. Click on ctrl+left or ctrl+right to rotate the device so you can see how it looks in portrait or landscape. Its one of the best iphone simulators you can get on windows - short of installing a mac OS as a virtual machine and running the iOS SDK on it - which violates apple's software licencing rules. You won't be able to use it for building and testing full blown iphone apps, but for simple cross browser checking of websites its just the ticket.

AND it's built using Adobe Air so it's cross platform compatible with Windows, Linux and Mac OS. Sorted!

AND its a LOT easier to get running than the official Blackberry emulators which require you to get Blackberry MDS emulator working first - no simple task really! It took hours to get the MDS emulator working - sorting out JDK paths and permissions.

Fortunately, the official android SDK includes a great emulator, which works out of the box and can emulate all Android versions from 1.5 to 3.1. Very simple to set up, with only a little bit of fiddling to get the emulator working.
