When you're top dog, everyone watches for you to stumble and fall. The iPhone 4 is the biggest thing in the smartphone world right now. As a result, any flaws it has are bound to attract an unreasonable amount of coverage. That said, when huge threads on the Apple forum fill with users complaining about a specific issue, it is probably time to take notice.
"Is anyone experiencing a real slowness in the 3G data speed on the iPhone 4? I had a friend race me to a website with a 3GS, and hers blew mine away. I'm even getting some disconnects when I try to hit a webpage... my friends with 3G's and 3GS's are fine..."
iPhone 4 users in the UK have also reported this same perplexing issue, which seems to exonerate AT&T from any wrongdoing here. BGR reports that a YouTube video and a number of photos have been taken of the iPhone 4 beside a 3GS. The older phone has a good 3G signal, while the 4 switches over to EDGE or staggers forward at 30 kbps.
It is too early in the game to say that these issues persist in all iPhone 4s, or whether they are hardware or software-related. For the time being, spurned users should complain as loudly as they can. Apple will listen...eventually.
