Is the T1 a "straight" purchase - ie from a trustworthy/reliable retail source ?
Or was it picked off on ebay or somewhere, or a non-factory refurb ?
Because, although it sounds like a content, rather than device problem, this sounds way out of line - I suggest you contact the seller for a response/advice.
I have to say I've had every Sony from the x50's on, all used heavily, carted around extensively, had many a bang/knock, and never had any problems that weren't down to me, or content ....
P'raps I'm just lucky ?
