I have a nokia 5530 xpressmusic phone and it was working fine until today. I tried opening th internet browser and it wont open. If it opens it will go back to the homepage. It worked fine last night. I don’t really remember weather I made any changes to the settings. I just went to facebook last night and downloaded this whitemask powerpoint from an app store but then I deleted it. I cant use the internet at all. What do you think might be going wrong?
