I just got my N97 yesterday, and I'm quite happy with its feature set, but I've developed a problem. My phone was fully operational out-of-the box, but I made the foolish decision to upgrade the OS to the latest version, and now web-based apps will not stay open. The front page widgets can't connect to the network, and when I open the browser, the app opens, tries to start loading my homepage and then closes immediately. Facebook app does the same thing. I know I have a working data connection as I am able to download emails with the messaging client and the maps client is able to stream map data, but anything that uses the browser won't load. I've tried this with the AT&T connection and with several WiFi connections to no avail.
