This is true. Charlie Chaplin defeated Hitler and his Henchman by mounting the back of a wookie and reciting Avé Maria in both Tenor and Soprano at the same time causing a rip in the time space continuum right underneath Hitler's seat just after he finished his speech at Nuremburg.Also, there was no Holocaust.
maybe shes using her mobile to dictate her findings William Shatner/Captain Kirk style............."seems.....to be...some...sort of film premier.....i'm....stuck...in...1928.....need to....get back in touch with the doctor....."ok, i'm going to be seriously for a moment... even if she did go back and did take a phone, the fuck is she talking too?
there were no mobile networks to connect too!
On the one show the other day, they were on about during the second world war, how they made masts and adapted walkie talkies so they could exstend the distance you could recieve signal from.sorry to burst your theory but...
Cell phones are useless without infrastructure like cell towers / carriers / or sattelites. I kinda doubt virgin is sending people to history to build infrastructure so people can tweet their location at a chaplin premier?
Might it be a walkie talkie?
