Has there been some kind of an Android OS push?
My handset has not been right for a week, throwing out relatively minor tantrums in SMS use (but the SatNav application, which has been heavily used this week) has behaved faultlessly.
This evening I had to reboot the thing three times, and it was only after the third reboot that SMS fell in to place and started to run properly.
I did uninstall TweetDeck, force a reboot and then reinstall it from scratch.
Since then everything’s fine.
So maybe it wasn’t the phone; maybe it was TweetDeck?
Anyway, if anyone hears of anything…
