You can build for the simulator, but it won’t give you a true representation. If you already have a mac than save for iOS basic or see if you can obtain a student license.

Unluckily, without buying at least the $400 Unity iOS addon license you can not develop for iOS using Unity.
Thats the minimum required to build for the Simulator.

For real testing you will need to get an apple dev license for $99 /yr from Apple on top as thats the requirement to create device builds and naturally an OSX 10.7.3+ Apple computer for the iOS SDK
