I was recently having issues with my phone not being able to use 3G, and I thought it might have been a firmware or possibly hardware issue. But after troubleshooting for some time, I found that it was in fact applications crashing or firmware bugs.
Hearing more and more reports of network issues with 3G and iPhones, Wired Magazine decided to do a survey of 3G coverage across america. The results are pretty interesting.
Recently http://Wired.com asked iPhone 3G users all around the world to participate in a study, which involved testing their 3G speeds and entering their data on an interactive map. The purpose? To gain a general idea of how 3G was performing — where it’s best and where it’s worst — in light of widespread complaints about the handset’s network performance. More than 2,600 people participated (wow!) and we’ve diligently cleaned up the data to present it to you here.
