Antenna issue: With all of the hubbub this week regarding the antenna issue, I am glad it has not impacted my use. I think you may have to really go out of your way to make it happen. That said, it is clear that this is a black eye for Apple and they need to address it. As I was writing this entry Apple released a statement defining the problem as software related and (http://www.apple.com/pr/library/2010/07/02appleletter.html) they will be issuing an update in the next couple of weeks.
I have used an INCIPIO silicon case with my 3G and 3GS, and plan to do the same with my iPhone 4. I used my 3GS case initially which was loose on the iPhone 4 and was looking at a silicon case from Zagg, the makers of the Invisible Shield. I was in Montgomery Mall on Thursday and saw an Invisible Shield booth right in front of the Apple store, what great marketing. I wanted to stop by but there was a line and I did not have time to wait. Bottom line, with or without a software fix the antenna issue won't be an issue for me. Yesterday, I happened to be at a Radio Shack looking for a weird battery, anyway I saw they had an iPhone 4 INCIPIO silicon case for $14.99 and I purchased it. I think this is a great case, although the included screen protector is so so. I find it very bizarre that Radio Shack is not promoting their cycling team with Lance Armstrong in their stores by selling team stuff. It would help promote cycling as well as their brand.
Battery: In the first couple of days of use, I got concerned about battery life, but that seems to have worked itself out after several full charges. I can now attest that battery life is much better than my 3GS and by 5 PM I am still above 50%. Unless I am using the iPhone 4 heavily during the day it looks like I can forgo my midday charge. Yesterday, I used it pretty heavily with over an hour of Slinging and by 9 PM I still had 25% left.
All in one inbox: I love having access to multiple Exchange mailboxes in one view. I can't even do that with Outlook 2010, or at least have not figured out how to create a view with my two Exchange accounts. Unfortunately, Apple still does not support flags, how do they prioritize email in Cupertino, maybe they don't or they use folders which I think only addresses part of the email organization problem.
And of course no tasks support which fits right into my flag bitch. I use the TaskTask application which works very well, but iOS 4 broke it http://www.tasktaskonline.com/TaskTask/Blog/Entries/2010/6/21_iOS_4.0_Compatibility_Problems.html and there seems to be no fix in sight. For now I am back to Toodledo using the Toodledo Sync Tool for Outlook (it works with Outlook 2010) but you can't set reminder times in the iPhone app which is a very bizarre omission...
