Hi, I'm thinking of purchasing an iPhone to use only in Wifi hotspots (for now at least) to browse the web and make calls through Skype. I understand that I would need to purchase the voice and data contracts initially but would like to cancel them and keep the phone. I also understand that I would have to pay an ETF of $175, right? Has anyone done this and is this possible? I would need to use an app to create a fake APN, or is this not necessary? Any tips would be appreciated! Thanks.
