Like every other iPhone owner, I update my device to the new iOS 4.0.1 today. After some initial upgrade woes, it was up and running and like everyone else, the only new aspect I could see was the that signal bars are now taller.

But it may have done something much, much more. 

I’m not going to write this on TechCrunch yet because I simply haven’t tested it enough. It’s only on my iPhone 4 and only in my apartment so far. But here’s what I’m seeing: 4.0.1 seems to have resolved the death grip issue on my device.

Yes, you read that correctly.

I’ve had the iPhone 4 just about a week now. I’m going to post a full review on TechCrunch, hopefully tomorrow. But I wanted to jot down a couple quick things I’ve noticed about the antenna issue here.

1. It is definitely real (at least in the phone I have).
2. It is definitely only in the lower left corner (the right corner does nothing to degrade the signal).
3. At first I thought it might just be that the bars were dropping but the connection was fine. But after some fairly in-depth testing today, that’s not the case. Calls will drop, data will stop.
