openmedia: Just popped a Skinny SIM in my S2 and I assumed it worked because I still had the Telecom APN defined.
I was suppsed to get a message with APN settings but it never turned up.
I find you sometimes get a text and sometimes don't. But if ever you need the settings (you probably will for mms) go here http://support.skinny.co.nz/app/answers/detail/a_id/236/~/mms,-data-(internet)-settings
