Hello i've got problem with my htc one x signal problem,previously i had desire hd at 3 network and everything with the coverage was allright,since i got one x there is a problem with the mobile network,its very poor and it just keep loosing saying no service,i have tried to call 3 that they cant exchange that handset for me because the 28 days of warranty have passed still im not sure if this could be a new micro sim problem,shouldn't the warranty be longer if its the hardware problem?
