One of the main talking points about Apple's we'll-get-it-here-eventually iPad has been its use of the micro-SIM format. While Australian telcos have said they will support the format, it turns out you can get similar results with nothing more than a pair of nail clippers.
Australian software developer Secretlab has posted a picture on its blog showing how a Next G sim was cut down using only a pair of nail clippers to fit the iPad's 3G slot. Space-saving considerations aside, it has been widely assumed that the use of the micro-SIM format is designed to force people to purchase a separate account for 3G access on the iPad. This kind of hack makes it much easier to adapt an existing cheap SIM (and its associated plan) if you're so inclined.
