[Aaron Nelson] tipped us off about a simple hack to use an iPad SIM with an iPhone. You won’t be able to use the iPhone as a phone, but the relatively cheap $29.99 for unlimited Internet was his goal. He used an old plastic gift card to cut out an adapter for the iPad’s micro SIM so that it will fit into the iPhone’s SIM cradle as seen above. From there he used a web service via the WiFi connection to enter “Broadband” as a custom APN.
