Well, one day I was rebooting my phone after deleting an application and when it was done the reboot I noticed that my browser which came with the phone (Internet Browser I think it was called) had disappeared and since my WiFi has also not functioned properly. I can still browse the internet via HotSpot browser but am unable to access Blackberry app world.

I was going to restore it from my old backup but unfortunately you need functioning WiFi to do that, so yeah..

Any ideas what's wrong?
