I am also waiting for Iphone5.

I have couple of questions regarding the use of Iphone and Ipad in Nepal.
Does ipad work in Nepal? Probably I have to buy a router (and modem?) to work in wifi. I dont want to buy many accessories for a month. How about wifi hotspots. 
And for iphone, what is the best way to use without any roaming charges?

Please reply who have been there.
