Yeah..that cordless telephone is there because the movie is depicted as having happened after death. You know how theres that Muslims belief that when we die...all that we did in life will be shown to us ? Something like that is depicted and if you listen carefully the one who is supposed to place Mr.Jinnah somewhere in the Hereafter says 'they've sent these wretched computer models from the FUTURE'
Hey Bro ! If I could ask you to take some time out to watch this movie 'Jinnah'. Its a biographical account of the Founder of Pakistan and the Pakistan Movement. I found it uploaded here on Youtube : http://www.youtube.com/watch?v=e13IGsw0wGw
