What iOS 4.0 feature do you use most?

Fast app switching. I keep on double tapping the home button on the iPad too now. The iPad is CRYING out for fast app switching and multitasking.

 

1. Fast app switching

2. Portrait orientation lock

3. Folders

 

Yes, I too am loving the portrait lock!

Also, the majority of my apps are in folders so I love those too.


Surprisingly, I don't use multitasking/fast app switching as much as a used to on the beta on my 3GS.
It's still nice to have, though.

 

Me too. I can't wait for iOS on iPad.

 

What he said.

 

Most useful is fast app switching. LOVE it.

Least useful is folders. Only have 1.

 

I'm a big fan of folders and "multitasking" as well. And the ability to have different wallpaper for the home and lock screen is nice.

 

I didn't think I would, but I've been mostly taking advantage of Fast App Switching more then anything... It's amazing how much more productive I can be by having the option to jump back and forth between things so quickly... it's really changed the way I use my phone.

Spell check comes in handy all the time.

I LOVE the unified inbox... I've just recently managed to break my habit of backing out of the mailbox after I check it to log back into another one.

I'm using folders but am having a hard time defining an organizational scheme in which I'm not constantly losing track of my favorite apps.

 

I'm only on a 3G, so I'm a little more limited than some other folk.

1. Folders
2. Turn of cellular data.

And I think that's about it. iPhone 4 can't get here soon enough.

 

Unified inboxes for mail.

Multitasking is nice, but rarely saves the day.

 

Amen to that! The iPad needs it more than the iPhone did.... hurrry up!

so my answer:
1. Fast Switching
2. Unified Inbox
3. Folders

These are all HUGE and have made me like the iPhone much more, not to mention the iPhone 4 is amazing.

 

After using an iPhone for over two years, it's definitely the fast switching that I'm enjoying the most. Only problem I have with it, is just remembering to use it

 

Multitasking and Folders.

 

I'm trying the unified inbox. Any way to 'color' them like the calendars so that each inbox is a different color? It will be easier to differentiate in the unified inbox.

 

1) Folders
2) Portrait Lock
3) Fast Switch/Multi-tasking

 

Fast app switching/multi-tasking hands down.

 

Since making this a habit in my iPhone use, it is by far my favorite and most used iOS4 feature. Incredibly fast with the iPhone 4.

 

Fast app switching, definitely. I wasn't a fan of Apple's multitasking solution when I read about it, but having used it for the past 2 weeks, it's all you really need.

Folders...meh. I have them on there, and I use them, but only because I feel like I'm supposed to, if that makes sense. They don't really make using the iPhone any easier for me.

Haven't even touched the rotation lock yet. A complete non-issue for me.

 

Definitely the new dock. I'm using it 24/7.

But right now since I have a 2G iPod touch it's spell check and persistent WiFi. When my iPhone 4 gets here I'm sure it'll be multitasking.

 

Video calling - whether it be facetime or fring, I'm always in touch with my cat!

 

Where are all the multitasking and fast app swiching naysayers now? Eating a very large slice of humble pie that's what. Apple should have had this since iPhone OS 1.0; it makes such a massive difference to the experience.

 

I use that feature that lets me accidentally end a call with my face or the feature that will kill my signal so I don't have to put it in flight mode.

What? Those aren't SOFTWARE issues? Hmm.

 

Humble Pie? Hmm.

You are right though, Apple SHOULD have had that implemented since iOS 1.0... That's what everyone had a problem with.

 

Folders have really cleaned up my Home Screen. I didn't think it was a big deal at first - but once I made one folder I decided that I really liked having them and now I have my Apps in five different folders. I also enjoy changing around the Wallpaper on my home screen. I enjoy it so much I now have two Wallpaper Apps.
