I've now have several days under the belt with iPhone OS X Update 2.2. The good is the Google Maps application with Streetview. In my opinion, Streetview works better on the iPhone than it does on a Mac or PC. It's clear, fast, smooth, and easy to use.
I also like the single-click home key push that takes you back to the first page on the Springboard. I didn't think I would use it that much, but I find I use it a lot.
The improved HTML handling in the email application is a nice touch. Whereas I used to pinch to expand a page, it seems to render that way naturally now.
The bad is that I am convinced the battery life is not as good as before the update. Apple has over their various updates made significant improvements to the power management on the iPhone. They seem to have taken a step backwards with this update. I had finally gotten to the point of getting a full day on the battery with moderate use. Now it seems that battery life has been reduced by 20% or so.
What say you?

iPhone November 2008
It has been awhile since I posted to this blog for the primary reason that I did not have anything significant to add to the conversation about what a good or terrible phone the iPhone represents. However, there are a couple of items that I have not seen mentioned that I think warrant discussion: 3G coverage improvements; iPhone battery improvements; AT&T's Wi-Fi hotspots; and blogging applications.
I live in the Dallas/Fort Worth area and when I first got my iPhone 3G, the 3G coverage was marginal at best. That is, in many places, a 3G signal was not available; where there was a signal, it was so weak that the phone would switch back and forth between 3G and EDGE; and when you did get a signal, it would suck the energy out of the battery in no time. Over the last month or so, that seems to have changed. With the release of the 2.1 update, the 3G radio seems more stable. In addition, it does not seem to drain the battery as fast. However, the biggest improvement appears to be the 3G network itself--finding a strong 3G signal now appears to be the rule instead of the exception. Quality has improved as has stability. Speed is exceptional.
Along with these 3G improvements has come a related improvement in battery life. I can now typically get a full day out of a charge, something I could not do just a few months ago.
Now for the bad news--AT&T's Wi-Fi hotspots work terribly on the iPhone. First, the hoops you have to jump through just sign on to the hotspot is a genuine pain. You connect by Safari, fill out your phone number and agree to the terms and conditions. Then AT&T sends you an SMS message with a link to use for access. However, half the time, the link is not live (requiring you to enter a really long URL manually into a browser. Another quarter of the time, the link is bad and will tell you that you cannot connect and to try again later. If you should be so lucky to connect, the connection is flaky. That is, when I go to open another Safari window, AT&T will ask me to go through the sign-in procedure again. By this time, it is just simpler to turn on 3G.
Other than that, not much has changed. The iPhone still crashes periodically, although less than when first released. Some apps are good and some are bad. I have been trying out the free blogging applications. I tried to post this using LifeCast, but once the entry was completed it would not upload and I ended up having to manually enter the post online. Therefore I wouldn't recommend LifeCast.
WordPress is an outstanding free blog, but is limited to posting to the WordPress site only. However, it is easy to use, full featured and works well.
Finally, BlogWriter Lite works well, no labels or tags, but will allow you to compose on the iPhone and then post to a blog. I use it for a BlogSpot blog and it works great. The only problem is that it will allow the use of only one blog (I have four). I am willing to buy a blog app, but the choices at present seem to have significant bugs judging from the comments, so I will wait awhile longer.
What are you thoughts on 3G, battery life and blog applications? I would like to hear.

iPhone 3G Bug Research
Since getting my iPhone 3G two weeks ago, I have found that there are a variety of problems with it. Many of these problems have been documented as individual issues with the new phone. They have included battery drain problems, especially with the 3G radio turned on; crashes of a variety of applications, but mainly with applications added from the Apple AppStore; and a variety of memory leak problems that lead to the operating system running slower and slower until the only way to fix it is to perform a hard reboot by pressing and holding the on/off and home buttons simultaneously.
I experienced all of these problems at one time or another. In many cases, I was having to perform the hard reboot multiple times a day (not to mention frequent battery recharging). Therefore, several days ago, I undertook a series of experiments with the iPhone by turning the various radios on and off under different circumstances to see if they had any impact on the identified problems. Since I don't use bluetooth, it has always been off. However, I have worked with the combination of 3G, EDGE, and Wi-Fi in various configurations.
The results indicate that the problems occur when the 3G is on. First, with 3G off, whether or not the Wi-Fi was on, I did not experience the frequency of crashes and memory leaks that were experienced when 3G was on. Indeed, I have had 3G off for a couple of days now and have now and have not had to perform a hard reboot once. While numerous application launches are slow, they are consistently slow--there is no degradation in performance. From this I conclude that the slow application response (lasting to five seconds or more in some cases) is a separate problem with the configuration of the OS.
Battery drain with 3G off seemed to be on a par with the 1.1.4 version on the generation 1 iPhone. While this is not surprising on the one hand, it is when I have had discussions with numerous people complaining that the 2.0 version on the generation 1 iPhone seemed to have faster battery drain. My suggestion is that unless 1) you are accessing complicated, non-iPhone optimized Web pages; or 2) you have a need to access the Internet and talk on the phone simultaneously, leave 3G off. Leave it off at least until Apple releases an update to 2.0.
To be sure, I still experience crashes--especially related to Safari--but they are much less frequent. This leads me to believe that the Safari crashes are due to a cause separate from the other application crashes. (Speculation is that the other application crashes may be due to the DRM used in the SDK.)
Another issue isolated by these experiments is the communications instability. With 3G on, the iPhone appears to have significant problems locking onto a "preferred" radio--EDGE, 3G, or Wi-Fi. As a result, the phone experiences numerous drop-outs, causing the phone to pick a back-up communication radio and re-establish communications. My research indicates that this happens when the phone has the screen turned-off for any extended period of time. It also occurs when the signal is marginal (not sure what marginal is as yet). When the situation occurs, the iPhone "thrashes" among the various available radios. However, it seems most pronounced when the 3G radio is on. When the 3G radio is off, it will still take a few seconds to lock onto either EDGE or Wi-Fi, but does not take that long. When 3G is on, it seems to take forever to lock on. Whether this is the radio, or the handshaking that goes on after lock to establish an Internet connection is unknown.
The result of all this is leave the 3G off if possible until Apple has had time to work through the various bugs in the OS. Your thoughts?
