3. Battery Life In Normal Operation

These results are not scientific. I get 4-5 hours of battery life just using the iPhone for various functions: phone calls using mixture of phone ear speaker and microphone, wired and Bluetooth connected headset; email including viewing attachments, Web browsing, weather and stock checks, listening to music or watching a little video.

Aside from the display, WiFi and Bluetooth eat up battery fastest. This is not surprising, since the same thing happens on laptops and notebooks.

Reconsidering The Camera

I wasn’t too crazy about the two megapixel camera in my initial review of the iPhone. Well, I’ve been able to play with it a lot more and now I’m a real fan. Remembering that there is no flash, indoor photos are not all that great. However, take the iPhone outside and the photos are near spectacular. Here’s an example.

This photo was taken toward evening on July 4th. The group of "fireworks maniacs" had their backs to the sky. The colors are spot on and the contrast and brightness are also quite accurate. If the photo doesn’t look like I’ve described it, it’s possible your monitor isn’t properly calibrated.

A Serious Problem

This example applies to all IMAP folders viewed with the iPhone’s IMAP client and to all folders on the IMAP server. However, to focus on the biggest concern about Apple’s implementation of IMAP on the iPhone, I’ll focus on the Inbox folder.

When you use the iPhone’s IMAP client, a message deleted from the iPhone’s IMAP Inbox is marked for deletion and then hidden in the Inbox. Additionally, a copy of the message is placed in the iPhone’s Trash folder. This makes it look like the message was deleted by moving it to the Trash folder, but this is not the case. The "deleted" message is still in the Inbox and marked for deletion, even though it’s been hidden.

Both of these actions cause changes on the IMAP server. If it has not yet been synchronized to the server Inbox, the message is so synchronized. The fact that the message is marked for deletion also is synchronized to the server. The copy of the message in the user’s client Trash folder is synched to the user’s IMAP server Trash folder. So, on the server it appears that there are two copies of the message, one in the Inbox folder marked for deletion and one in the Trash folder.
