iPhone OS 2.1 on 3G had signal problems too
Once upon a time, iPhones had an OS update known as version 2.1, and there was much rejoicing. Actually, there was a little bit of the rejoicing and a bit more of the griping. What was the griping about? Well, some of you kiddies might not remember this, since it was so two years ago, but the story may ring familiar: it was all about degrading signal indicator issues with the iPhone 3G. Part of what that article notes is the existence of the field service test mode that was, then, present in the iPhone OS. It used to be pretty trivial to access this mode, which would give us gadgety techno-nerds information like more detailed signal strength. A feature like that would be dandy for troubleshooting the iPhone 4's recent disappearing bars problems, but Apple decided to remove access to test mode in iOS 4. Seeing as this issue cropped up in the early days of the iPhone 3G, AT&T's response to it then seems to indicate that, quite simply, a software update will fix the signal strength indicator problem in the iPhone 4. Let's just hope it comes out sooner than later so that we can stop talking about this issue already. Thanks Ilkyone for the tip!
