My Torch developed a problem where some of the keys on the keyboard stopped working. Nothing prompted this error - they went from working fine to not working at all within about 30 mins. It wasnt all the keys just random ones.
Anyway, I was sent a replacement and it's hard to explain but it 'feels' different. The whole thing feels more sturdy were as my old unit was a little 'loose'.
Also, web browsing etc seems a lot faster. So I was wondering if the phone has been changed slightly since it was first released!
