Anyone else in the DC area experiencing slow data? Particularly the Downtown/White House area? Ever since I got the iPhone4 It's been blazing fast for me. Yes, when I "death grip" it my bars do go down a bit, but never completely down, but my data has always been fast. But today for some reason it's very spotty no matter how I hold it or on the table. Sometimes it's fast, but most of the times webpages are just hanging and then will finally load up. So just wondering if anyone else in DC having problems.
