Hi 1st of all what software/firmware version have you got in the phone ? because it could be theres a possibility that your phone needs a software/firmware update ! a sure fire way to tell if this is the case is just recently has your phone slowed down i.e internet slower when you send a text does it take longer to send than usual etc ! because every so often a phone needs an update its a bit like a service on a car to keep it running on top form but without actually having a good look at the phone theres not really a way of telling if this is the problem or not so my advice would be to pop it along to someone who knows about & is qualified to repair phones & let them have a look .. hope this is of some use to you .. sly
