Since last night I noticed on the notification bar, a caution sign w/ an exclamation mark saying "Unexpected Error; please click here to help us solve the problem" & whenever I did click it, it would reappear.

This morning, it disappeared but now my internet is not working. The bars are fine and it's connected to my data service. Whenever I would run an app, it would always force close. But when I connect to the internet itself it works just fine.

I used an app and all it would say it "Unable to connect"

Please help! I also tried doing a settings reset, taking out the chip and sim card and leaving it out, constantly restarting it but nothing ever helped. Please reply asap!
