I had a blackberry storm as an upgrade about a month ago and I hated it. Worst phone I had ever had, battey would last about 10 hours, signal was terrible, and it was a horrible phone to use.

I sent it back and replaced it for an N96, which is by far the best phone I have ever had. Some people do say that they freeze occasionally, but Nokia have released updated software for it so you can upgrade it, this fixes any freezing problems.

Rich_bloor, make sure also that you dont have lots of applications still open, hold down the menu button for a few secs and that will show u what is open. You should just have menu and standby in the list
