iPhone 4 could've been the best smartphone ever. I would have bought one
blindfolded.
The antenna completely ruins it!

Now i'm gonna wait for a confirmation about fixed versions from iFixIt or other blogs.
Any else felt the same way?
I DID feel this way. And I do still feel like it "ruins" the phone in a way, but only because the rest of the phone is so damned awesome. I think that's what people are so in a spin about... is the phone is so phenomenal, but this one lousy thing had to taint it. It's like dating the perfect girl and then finding out something bad about her you just can't get passed.
In any case, at this point, I think I'm over it, and I'm going to give the iPhone 4 a try anyway. I mean, I have 30 days to evaluate it. If it's just not working out, I bring it back, just like The Antenna Song says. No harm, no foul. For me, if the case remedies the antenna issue, I'm good. The iPhone 4 looks awesome with no case but there's no way I'm gonna be carrying that thing around in my pocket everyday without a case.
The bigger issue I had a problem with was the proximity sensor. Before the press conf, a mention of that was on my "must" list. And I honestly didn't think Steve Jobs was going to mention it, but he did, and I was very pleased about it.
Between him saying they're working on the prox. sensor, and using a case to alleviate the antenna issue. That's good enough for me. And again, I have 30 days to work with this device and see if it's going to work the way I want it to.
As I was saying, I feel the rest of the phones features and just the overall usage experience is too damn cool to not give it a shot.
