So I Limerained as soon as it was released. Since then I've been experienceing weird WiFi problems. After a reboot it works, but at some point, and for no apparent reason, it will show the connected symbol in the top left, but pages won't open, Cydia, Facebook, BBC and other apps won't load/refresh BUT Push will still work. The only way to get it working again is a respring, or sometimes even a reboot. Any ideas?
