funny you should say that... I have exactly the same phone, Ive had a viral infection all week, and decided to get loads of night nurse down me and get to bed very early, feel asleep at 7pm, but before I did, i changed my phone time on my Nokia 5800 manually... what has it gone and done, changed it automatically! Doh, so I woke up thinking it was half hour, but really it is half three, and now i cant sleep!!!! aaaarrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr
