i heard that iphone is coming to india, but i want to have it before that. I am goign to Germany befoer that for my project. Can i by iphone there at Germany and wait for vodafone in india to launch it officialyy. so that i can use vodafone sim in the iphone that i bought from Germany. Also will it be useful in some other way like ipod and browsin till i don’t put a sim in it??
