Kitanai: Need microSIM + 3G
There's nothing on their site, but latest rumour is that they'll be doing both of those today.
Might call them up later if they haven't updated their site to find out where 3G is available.
They did a press release yesterday, will be selling micro-sims at DSE from today - $20 with $20 worth of credit on their sim, and their 3g network will stay on from now till launch... Which should also obviously be coming very soon.
