Have already used in-air wifi "officially" in Delta in Dec end2012/Jan2013 (was free!!). It worked brilliantly. They were even having a test phase of gsm calls from your mobile in some other planes at the time (not the one I was on though).

I think if electronic gadgets of ours could really cause security concerns they would really not allow it at all onboard, like they dont allow gas lighters, firecrackers & similar stuff. I dont mean to say that mobiles wont cause interference. They will, but if it was really life threatening they would not allow them to be in the hands of people for potential misuse.
Anyways newer aircrafts are toughening up against interference so all this should be gone in a few years

Good mythbusters video on the topic at hand!
