I’ve now had my iPhone 4 for several weeks, and wanted to re-visit these thoughts, to see if I’d changed my mind on anything.

First, the iPhone 4 is pretty awesome. The display is gorgeous and battery life is much, much better.  The responsiveness of the camera has me using it all the time, and the ability to multi-task, even in limited ways, is great.

The rubber Bumper case is annoying, because it clings to the fabric on the inside of my pockets, which makes the phone hard to get in and out.  This leads to me not wanting to use it, which in turn means I will have to deal with the antenna issue and the fact that I spent $30 on the case.  Apple has just dealt with the $30 portion of that problem.

Under 4.0.1 I no longer ever have 5 bars in my house.  I live in San Francisco.  Coverage has not changed.  It’s good to have a better understanding of how poor AT&T is here, and I wish I had my phone configured to display -db, as the Anandtech people do.  I’ll look into that.

The antenna issue, whatever Steve Jobs, John Gruber, et al. say, is both real and a hardware flaw.  I have now spent quite a bit of time holding other people’s iPhones, as well as the demo units in the store.  I have found phones that will drop from 5 bars all the way into “Searching…” and I have found phones that, in the exact same location, will drop from 5 bars to 3 and no lower.  I do not see any way of telling them apart, other than holding multiple phones in the hand.  Note that, in order to truly tell, one must hold the phone for upwards of one minute.  In shorter amounts of time the phones look identical, as they will all drop roughly 2 bars.  Only after a longer time will some phones continue all the way down to no signal and the battery-destroying “Searching…” mode.

The proximity sensor issue is also real, but very, very tricky to diagnose or understand, as it seems to only happen after the sensor has been activated.  I have only had it happen one time, where a call ended surprisingly and I looked at the phone and realized the screen was on.  I don’t spend a lot of time on the phone, making only a few brief calls a day, and encountered the issue on a more lengthy call.  I suspect this is fixable in software.

The reflective clarity of the Apple logo on the back is amazing.

The iPod app is nicer now.  I don’t use it too often, though I am starting to as I grow less afraid of my battery, but the subtle interface changes, which mostly present more details on each screen, are much appreciated.

I love being able to see the percentage of battery remaining rather than simply the icon.  This has been possible since the 3GS, but is new to me.

My best usage time on the iPhone from 100% charged to shut down is 6 hours 34 minutes of usage and 38 hours 21 minutes of standby.  That, to me, was impressive.

And, on a very specific note for one person, let me say this: don’t put your phone in the same pocket with your keys.  That would be stupid.
