I am looking for the cheapest way to test websites and HTML email on a device that behaves like "the latest iPhone running the latest iOS". I have heard that the iPod Touch 6 is supposedly identical to the iPhone 6, except for not having a GSM radio chip.
From a developer perspective, what are the differences between the iPhone and the iPod Touch? Do they run the exact same OS? And if I eventually move on to proper iOS apps, will these behave exactly the same on an iPod Touch?
iPod touch runs iOS exactly like an iPhone... same updates and same apps, the only thing is that you can't use the hardware that the iPod doesn't have (GSM).
