Try this - Go to settings-connectivity-destinations-internet-options-delete , then delete all your access points. Turn off phone and remove sim. Start phone without sim, once stat up has finished remove battery, leave for a couple of minutes, re-insert sim, start phone and go to menu-applications-phone setup-sett.wizard and let it run, if it says settings already defined ignore and con tinue, let setup wizard work, but when you get to define mailbox stop it (unless you want to define a mailbox) Now go to your homescreen and select web, phone should ask if you want to choose a connection, select ok and you should be ok !(not stating this as a great fix, but I've been having problems with connecting the communities app all day, and this solved it !)
Good Luck
