For whatever reason, within the last two weeks I've been experiencing 3G data drop-outs. At first I thought it was my phone, so I would do a restart and it's fine. A few more days of this, I realized I could solve it by switching to airplane mode and back. After two consecutive weeks of this, my patience has worn thin. I've never had data problems before, and I'm confused as to what's causing this. I thought I'd ask my fellow DC iPhone users if they're experiencing similar symptoms, or perhaps my iPhone software needs a refresh of sorts. It's been happening in Northwest DC and I'm on a 3G (non-JB, no ridiculous tether/mms hacks). Voice calls are not affected. Any insight/suggestions is appreciated. Thanks in advance.
