For the past 2 days, I've been unable to load any websites from my desk at work from my iPhone 4. Sometime I can get a page to half-load but it just never will fully load. I have between 3-5 bars. With my 3GS, while I would have less bars at my desk, I never had a problem with data speed or reliability. I've reset network settings. I'm going to reluctantly try a restore tonight. Any one else have similar issues or have any suggestions for things to try and fix it? Thanks.
