I wanted to purchase an unlocked iPhone 4 (or used 3GS) here in Canada and use it for a few months as an 'iPod Touch' before my cell-phone contract expires (i.e. use all the functions apart from the actual phone) But from what I read on the Apple website...: " Its easy to set up. Get a compatible SIM (iPhone 3GS) or micro-SIM card (iPhone 4) and select a plan from the carrier of your choice. Then insert the card and set up your iPhone using iTunes on your Mac or PC. With a few clicks, you can start making calls." ...it seems like I need to have an active sim-card in the phone before I can even connect it to iTunes. So just to clarify - do I actually NEED to purchase a cell phone plan/sim card before I can use the iPhone (sans phone)?
