Okay, so I upgraded to iPhone OS 4 yesterday. A pretty painless process that took me about 20 minutes including the download. I read reports on Gizmodo.com that some upgrades were taking more than 2 hours to complete. Sorry, if you had to deal with that.

Anyway, I’m adjusting to the new iPhone OS 4 interface experience. Overall I’m pretty happy. However, I’m feeling like if I had never used an iPhone before upgrading to OS 4 I’d be much more nimble as I move through the interface. Right now, I find myself reverting to old habits from version 3 of the iPhone OS. With some time, I’m sure I’ll be up to speed and hopefully forgetting many of my subconscious habits from OS 3.

I do have one gripe when it comes to multitasking application management. It’s how Apple’s decided to handle the closing of open background applications in the multitasking menu. I’m not a fan (nor will I ever be) of having to hold my finger on the open application icons to initiate the closing process. To close each application that’s open by clicking on the minus button that pops up on the app takes far too long. To me, a much more elegant and quicker solution to closing down open applications would be to simply let me swipe the icon vertically to remove it from the multitasking menu, much like how I’d delete an email in the Mail application. Hopefully this is a feature that Apple’s going to implement in an upcoming update to the operating system.

Take a look at the screen grab below that illustrates my concept:
