No it is not dangerous. Attested to by the fact that many airlines have onboard telephony and wifi connectivity! The 'no phone' thing with some airlines is a hang up from the days when mobile phones were new and the effects on aircraft systems was unknown!
Heck - I even remember reaching V1 many years ago in a 340 when my phone started ringing loudly... I got a very pained look from the F/O (possibly becasue of my choice of ringtone) but the 'plane didn't drop out of the sky!!!
