I have a problem with my BlackBerry 9700 T-Mobile (Onyx). It sometimes turns off itself, but I don't even want to turn it off. It's very annoying, because we all know that BlackBerry needs a lot of time to boot up. It turns off when I leave it for a while, or when it gets a little vibration. Maybe it's the battery? Please help ASAP.

Sorry, english isn't my native language, so my english is a little broken. :s
