I’ve downloaded and installed iPhone 4.0 beta 4 on my iPhone 3GS. I’ve run 4.0 betas in the past but stability issues forced me to downgrade back to 3.1.3. But, beta 4 almost feels like gold master. I haven’t had any of the wonky issues I had with previous betas and I have a feeling I’ll be running beta releases on my main device until Apple pushes out the gold master this summer.
Many have written about the latest beta documenting some of the changes from the previous build. I’ve decided to publish my own screenshots of these changes almost simply for my own sake. I’ve always found it easier to find what I’m looking for if I know I’ve published it here rather than having to meander through Google search results.
The biggest change in beta 4 is the tethering option in the settings app. Attempting to turn on tethering prompts you to either call AT&T or visit their website to set it up. By no means is this confirmation, but it does lead me to believe that tethering might actually be coming to the U.S. sooner than previously thought.
