Hi,
I purchased iphone4s in april 2012, people used to say why is your phone always switched off. when i visited apple store, they checked/disgnosed and told me that the signal is dropping and replaced the phone in july2012.
Recently, after march2013, i again visited the store and replaced the phone again.
now with the new peice, i am unable to get the calls, till recently i used to get  calls for my job oppurtunities, but with the new replacement, i am unable to know, if it a problem with the phone or ishould move out of apple after all the embarasement for a year.
i have all the apple gadgets, but iphone4s really ***** my life.i have told them that i will pay the difference amount for iphone5, but the store guys says they cannot. with this problem, they now sold me a protection plan for 60 pounds.
I think, apple really ***** after steve jobs.if apple does not respond i am sure i will move to samsung 4
