One of my favorite revisions? The Calendar app, where you will be able to select any combination of calendars to display on your iPhone as well as allowing apps access to the calendar functions on the iPhone. Long overdue. What are some of your favorite additions/revisions?</p>

Hmmm, Monday iOS4 release, Tuesday I'm going to Vancouver BC for the rest of the week. I have a factory unlocked 3GS on T-Mobile, I wonder if I should defer my upgrade until I return? Maybe I'll upgrade my AT&T locked Test 3G phone Monday, to see if any mischief appears. Apple has been pretty reliable for upgrades (for me, anyway), but I don't want to brick my phone(s) right before travel. I'd hate to have to fall-back to my Nokia E63 if I hose all my main phones ...

The iOS4 GM seed broke one little thing I noticed. With the Apple BT headset you no longer get the green headset battery level on the main lock screen. It still shows in the upper right of the screen though.
