I have received my 09 SIM with its icelandic number.
SIM was not compatible with my Treo600 but was compatible with my new HTC Tytn
Incoming calls are free (140 countries) and thus, I'm placing my calls through Hiboo (www.hiboo-mobile.com). Calls are 0,40€/min to many countries (+80) (landline). Cheaper than 09 prices.

Of course, it means "two callback". But it's worth.
