Can a regular sim be cut down to a micro sim?

Is there any reason why i can't just trim down my old sim for my iphone 4s? (Other than the inevitable - but you could damage the sim) I have practised on a few old sim cards with a stanley knife and i must say it looks the part and fits... Is there anything different between the two sims that may damage my Iphone? BTW i have been very careful not to get any fingermarks on the sim!

Seriously, your best bet is to pop into a Telstra Store and ask them to give you a Micro-Sim. It shouldn't cost you anything at a Company-Owned Telstra store, however Licenced Stores can charge you a fee. But at least you know its the right SIM card for your phone (without cutting it :P)

We cant really recommend this... but if you must:

But you're better off getting a new SIM in a Telstra store which you can find here http://www.telstra.com.au/store-locator/
