Xperia T - stock, not rooted potentially reversed USB connection, now won't switch on

Hi
I'm wondering if anybody has any advice regarding my problem. I have looked here and tried what has been suggested.

My stock, never rooted, never flashed, Xperia T (think it was Android 4.3 but can't now check, the latest Sony rolled out) was working fine until yesterday. I was on a plane and noticed it had 20% battery life left so I plugged it into the onboard USB port. The problem is I think I hay have plugged the cable into the port the work way round – not the connection on the phone, but the actual USB socket. This should be impossible but somebody obviously had broken the port and it turned out the cable could be plugged in both ways! (I don't know if it was plugged in the wrong way round but is the only thing that could possible explain the sudden death.)

Could this have bricked it? I suddenly couldn't get a red light to show charging and holding down power on and volume up or down does nothing. I tried charging overnight via a wall socket when I got home but the result is still the same. Just a black screen and no sign of life. I have also tried plugging it into a computer with Sony's PC Companion but as the phone is not 'on', it can't be found.

Does anybody have any advice where to go from here? I'm more concerned about some recent data from holiday on the phone than the actual handset itself. If the phone is dead, is there any way to read the internal memory?

Thanks
