I've just got a torch and have been loving it until last night when a problem with my email/gmail seems to have developed.
I have 3 gmail accounts coming into the blackberry and since last night i cant see the text content of an email on any of the accounts. I've deleted the one of the accounts and set it up again, but still no joy.
I'd suggest a battery pull, as that what fixed mine (whilst the berry is turned on, take out the battery. Wait for 30 seconds, and put it back in again, let your Torch restart as normal).
Text for new emails was displayed, as was the missing text for old ones on my device.
