Is it just me, or does EDGE have trouble connecting these days... I've only had my iPhone for a couple of weeks, but just the past couple of days it's like my EDGE won't work for hours at a time... I still receive calls and texts just fine, but everything won't connect at times. I tried restarting my iPhone and making sure it has a full charge, but this doesn't show much change. Is it just me or is everyone experiencing this?
