What a bunch of Luddites!
I've never heard as much whining about phones 'cos it's too noisey - what a load of crap pretending to be an excuse. With thinking like that you don't deserve to have mobile phones let alone an iThingy - they might ring and disturb some TfL staff members' statutory nap.
Technical and financial difficulties aside, the myth that only terrorists and police will want to use phones on the tube perpetuates the excuse to do nothing.
Disclosure: Yes I'm biased - and offer no apology. I came to Hong Kong to design the Mass Transit Railway (MTR) phone system 18 years ago after doing similar work in New York. I read this article on the way to work - in the MTR. There are usually few if any people on the phone in the morning - that is normal voice traffic pattern. The afternoon is different - but then everyones at it.
I'm not sure I'd give the job to Huawei though... but that is another story. I guess the gov't has already decided better to outsource all UK jobs and the only employment opportunity in the UK will be delivering gourmet sandwiches to the few bankers not able to flee the UK/Euro bounus crackdown!
