[quote name='crunchewy']Apple released a statement that there is an issue with how the iPhone (all versions) report signal strength. They aren't making this up either, because this exact issue was noted in the review at anandtech.com (a very good read, incidentally). In short, the iPhone reports a 5 bar signal even when the signal is not actually that good, as well as when it is good. So you could show 5 bars, but it's a bad 5 bars, and then not much of the scale is allocated to 4, 3, 2 and 1 bars. Thus why you might see a dramatic drop in apparent signal strength. Essentially the scale is skewed toward the high end. They are going to release a software update for all iPhones that will make it report signal strength more accurately. Of course the haters have all come out claiming that this a ruse, but read the anandtech article and you can see it all spelled out for you, that this is exactly what the current iPhone firmware does. If anything, the way it currently reports bars is a ruse, and the update will change it to not being a ruse.[/QUOTE]
I guess it makes me a "hater" to call bullshit, but I'm having signal problems in places where I had no issues whatsoever with my 3G. Also, I have my phone set to show me the actual numerical signal strength (in dB) instead of just bars, and those numbers are running about the same as they did with the 3G -- I'm assuming it's not misreporting those. So sure, it may well have an issue with reporting the signal strength incorrectly. But that's certainly not the only problem.
