I have read and tried everything I can think of. My phone connects to the "network" fine. I am able to see Facebook posts and can update, I can view YouTube videos and post comments, and even play Words with Friends, but I cannot browse the internet. I constantly get the message: Connection failed! Unable to connect. Please review your network settings. I get this message with Opera Mini and the stock internet app that came with the phone. I have Sprint. I "reviewed" the network settings by doing the following: Turning off the phone and restarting. Disabling the Mobile network and re-enabling. I have tried 3G and 4G in well known strong signal areas. I have tried two different wi-fi areas. I have tried connecting to different web sites. I have turned off, taken the battery off, put back in and re-started the phone. I have not installed or uninstalled anything from the phone in over a week (and this started happening two days ago). I have also un-synced everything, and re-synced it. And finally I have tried updating my profile in the settings. And nothing. Anything that uses data works fine: Pandora, Slacker, FB, YouTube, games, Sync, etc. However browsing the internet is a no go. I really want to throw this thing across the room. Any other suggestions before I do?
