An update to my previous post on [Using an iPhone on 7-11 SpeakOut](http://themainframe.ca/2012/08/26/iphone-on-7-11-speakout-great/): The iPhone 5 works just fine on SpeakOut as well.
Since the iPhone 5 uses a Nano SIM, you’ll have to trim it to fit. There are numerous tutorials out there on how to do this. I followed this one (PDF).
Some notes on cutting a SpeakOut SIM to Nano-SIM size:
First of all, do this at your own risk. If you mess up, the SIM will be destroyed.
I just used a scissors and cut very slowly, using the iPhone 5 SIM tray as a guide.
If your SIM has 10 contact points (instead of the smaller newer SIMs with 6 contact points), you will have to cut into the unused contacts on SIM. Do this carefully and very slowly. Don’t cut into the embedded chip itself (see the tutorial above).
Contrary to what others have said, the SIM thickness doesn’t matter. No need to sand it down. It fits fine.
