Blackberry internet HELP?

[Take me away..]

Hello, so on my blackberry curve 8520, I have connected my internet wifi to it and it works. I can download apps from the blackberry app world, and all my applications work like facebook or what'sapp and stuff like that, but as soon as I go on the web browser it says: "Unable to connect to the Internet, please try again later. If the problem persists please contact your service provider."

It's been like that for about 4 hours now. What should I do?? And I also deleted my blackberry app world by mistake so I can't download it anymore :'( Please help! Thanx!!!

PS- I know this is the wrong category but no one was answering my question in the right category, and since here there's more adolescents they might know more.
Taking out my battery actually made it work! Thanks so much!

Disconnect to the wifi and try again, or do you have 3G?

Or if the wifi where you are isn't strong then it disconnects so make sure it is connected and that you have signed into the wifi with your password
If that doesn't work then take the battery out and put it back in.

Tell me if this doesn't work!

Edit-

Has it just stopped randomly working?
Do a battery pull.
Make sure the wifi on your phone is actually on.
If those don't work then ring your network provider.
