When I first purchased my phone in New Jersey, I was totally unable to replicate the problem until later in the day when I was driving up towards Albany, NY, where there was weaker signal and was able to replicate the issue. In any place where I have weak signal, I am able to replicate the issue. Here is how and why it hasn't really affected me.
Well, whats the first thing I did... I reinvented the wheel for myself and just started holding the phone differently. I felt it was appropriate, as I found myself cradling the phone more anyways. I used the phone naked for approximately two weeks before giving in and getting myself a screen protector and a rubber iFrogz case (sorry don't know the specific model). The second I slipped the case on, I have been UNABLE TO REPLICATE THE PROBLEM REGARDLESS OF MY LOCATION. It made the phone slightly more bulky, but the rubber covers all glass edges so I'm hoping if a drop occurs impact will be minimal. I use this case when I'm at work and don't necessarily have the phone in my pocket all the time. I recently received a bumper case and likewise I have been UNABLE TO REPLICATE THE PROBLEM REGARDLESS OF MY LOCATION. I know no one should have to have a case for their phone, but come on, every cellular phone has it's positive's and negatives. A $30 or so dollar case shouldn't be a deal breaker for most rational folks especially if you were really interested in all the phone offers besides just calling features. Sure, it's not an ideal situation, but most things aren't. Worst case scenario, really is that one year from now, everyone will be lining up for the iPhone 4G or 4+, with 100% resolved signal issues.
I recall someone somewhere saying how Apple, shortly after the news of the signal issue broke, was hiring approximately seven new employee's in the antenna department. I doubt this was damage control, and more likely a quick firing, for a grave oversight. Regardless, without a shred of evidence, I can almost guarantee you will not have this problem on any future iPhone, or apple mobile device for that matter, ever.
These are the mistakes that occur in the name of "progress". Ultimately, Apple was shooting for the stars and fell short, because my iPhone 4 get's better reception than any previous iPhone I've owned. Owner since 1st-gen. I'm able to connect to calls, when I have one to no bars, and rarely get drops unless I'm in a spot where I know I barely get service. I'm in the North East Kingdom of Vermont at the moment, with extremely marginal service, but have been able to take this iPhone where no iPhone has gone with me before. Yes, I do have to hold the phone differently when it's naked, and yes, a case has eliminated 99.9% of any antenna "bridging" problems, but I think CNN posting gross pictures of giant pieces of duct tape covering most of the left side of phone are just really in poor taste. A very marginal, less than quarter inch, by quarter inch piece of tape would resolve the issue if you did want to go that route and insist on using the phone naked.
Folks need to wait and see how Apple responds to this in the long run. They've just launched a massive product, people's order's aren't even fulfilled they aren't gonna just come out and admit this minor failure as the downfall of their device. A software update will likely fix the noticeability of the issue, and we will go from there. We will see a recall, an admission, apology, or possibly just nothing by the end of the summer.
