My wife just showed me a problem with her Viper today. She often has an issue where her apps (she specifically mentioned Facebook, bank app & groupon) can not connect to the internet (3G) but yet her browser works fine. Phone was plugged in when she showed me so I don't think it was a low battery/power save feature. I looked around in settings and didn't see anything obvious. The fact that the browser works indicates that it's not a data signal issue so I'm stumped.
