To 1.14 and below the old system development using unofficial SDK - Toolchain support development in the windows
Internet search iphone Toolchain, should be able to find a lot of installation tutorial
To the new 2.0 system now proposed to use official development SDK, support for the latest development in the mac system, (Toolchain under 2.0 is not mature enough)
Go to Apple's website, register an ID will be able to download, iphone simulator with the official SDK, developers easily
