You can drag items from your iTunes library to your iOS devices and they will automatically start syncing and installing. In addition to copying the item(s) you drag, a full sync is initiated. This occurs when your iOS device is set to automatically sync; you don't need to have it set for manual syncing for this to happen.
[kirkmc adds: Hmm... is this really new? I had never heard of this, but It's certainly useful. The hint submitted was about syncing apps, but when I tried other items, they installed as well. When I dragged an album, it synced, and when I checked the Music tab in iTunes, that album was checked in the list of albums. This is actually a very good way of syncing items to an iOS device. Instead of dealing with checking and unchecking boxes on the different tabs, you can just drag what you want to your device. This is different from a manual sync, where you only drag items; this retains automatic syncing, yet still allows you to add items to the device by dragging.]
Battery life with my iPhone 4S was very poor, and I finally discovered why: I'm using a battery extender case. The problem is that the phone considers that the case is a source of AC power, so if have iTunes Wi-Fi sync on - which only operates when your phone is plugged in - you'll be syncing more than you might expect, since your phone is technically plugged in.
The solution is to either turn off Wi-Fi sync, or use an external battery pack that has an on-off switch so that you can control when it is actually sending current to the phone.
[kirkmc adds: I guess this makes sense. Apple says that Wi-Fi sync occurs when "The iOS device is plugged in to power." But this should only occur if two other conditions are met: "iTunes is open on the computer," and "The iOS device and the computer are on the same Wi-Fi network." So I would think that if you're not on the same network as your Mac, then nothing should happen. Perhaps the phone is constantly searching for that Mac?]
A new feature in iOS 5.1 is the ability to access the camera without unlocking your iPhone or iPod touch (if you have a passcode set). To do this, press the home button, and to the right of the Slide to Unlock slider, you'll see a camera icon. The first times I tried, I couldn't figure out how this worked; I tapped the icon, but the screen just slid up a bit, then bounced back down. You need to slide the screen up, while dragging the camera icon, to access the camera.
Once you've done this, you can take pictures as you wish. In the bottom-left corner of the window is a small gallery icon, which lets you see your photos from your current session (you can't access other photos.)
You can go back to the lock screen by swiping down from the top of the screen, or proceed to the passcode entry screen by pressing the home button.
Note: this works with the iPhone and iPod touch, but not the iPad 2.
As you probably know, Apple announced the "new iPad," or iPad (third generation), yesterday. What do you think about it? Are you going to rush out and pre-order one? Are you definitely not buying one? Or are you on the fence?
Make your voice heard. Vote in the iPad 3 poll, and feel free to post any comments you have about the new iPad on that page.
When I tap the checkboxes next to items in your Reminders list to mark them complete, I usually want them to go away, so I don't have to scroll up and down, especially when I have a long list of things to do or buy.
To quickly force the marked items to move into the Completed section I noticed that if I slightly swipe to left or right so that part of the next or previous Reminders list appears, then release so that I stay in my current list, the completed items get moved over, and only the uncompleted ones remain.
In a recent hint it was mentioned that you could use your laptop as a lightbox for tracing artwork. Even better, you can trace on an iOS device, such as an iPad, with apps like Photoshop or Illustrator, if you want to trace something.
Using a screen forwarding utility like Air Display, you can use your iOS device as a secondary monitor for your desktop Mac. Simply drag your Illustrator/Photoshop/whatever window to that display, and you can walk around and trace whatever artwork you have displayed on the iOS screen. It servers as both the lightbox and the source artwork in one.
[kirkmc adds: I would be much more likely to do this with an iPad than a laptop, because of the iPad's glass screen. I guess you could even do this on an iPhone, if your art is very small.]
I just upgraded my iPhone 3GS to iOS 5, and played around looking for improvements.
Exploring the assistive touch panel, I found the 'rotate screen' options work also when portrait orientation is locked. Effectively, we can select any of the 4 possible orientations, and it will stay locked while moving and rotating the device. Switching apps will cause a reset to default portrait orientation.
While a bit complicated to reach, this will still be useful. I'm hoping for a shortcut or dedicated way to activate, like quad-clicking the Home button to rotate right, for example. I like the triple-click to activate white-on-black, for a basic night mode.
All of these and more options are available under Settings » General » Accessibility and enabling 'AssistiveTouch.'
[crarko adds: There are indeed a lot of useful settings in there. Explore them. It looked slightly different on the iPad, and the 3GS may have different settings from iPhone 4.]
I've always wondered how to delete music off of an iOS device running 5.0.x, which can be a pain what with iCloud downloading music to your iOS device, and then adding the same song a second time when syncing with iTunes.
When in the Music app on the iOS device just swipe like you would for deleting basically anything on an iOS device and you'll get the option to delete the song. If you have a bunch of songs you want to delete this will take some time to to but at least now you wouldn't have duplicates thanks to the new features of iCloud downloading the song and then iTunes syncing another copy of the song on the same device.
[crarko adds: The standard method for deleting line items in iOS comes to music.]
I have (somewhat reluctantly) configured my iPhone to receive my work email. This account uses Exchange (Active Sync). But when I'm home on the weekends or away on vacation I really, REALLY do not want to have my work email in my face.
The solution? Go into the iPhone's Settings » Mail, Contacts, Calendars » [Email Account] And turn 'Mail' Off. All of that account's email mailboxes disappear from my iPhone, never to alert me of what I have coming to me on Monday morning. But when I turn it back on, it's all right there - right where I left off. Very handy.
The same can be done for Calendars. I have not tested it with Contacts, but that may work, too.
[crarko adds: This works with any system where the primary data repository resides on the server; Exchange, IMAP, CalDAV. Just be patient while the app resynchronizes the data. I've use this as a troubleshooting technique, but this hint is also a clever idea.]
I've recently written a blog post on using S/MIME with iOS devices. I've found that settings things up isn't entirely straight-forward so I've documented what I needed to do to make it work.
The article explains how to set up your iPhone or iPad to send and receive encrypted emails via S/MIME. The prerequisite is an S/MIME certificate from a certificate authority. Some CAs provide them free for personal use. The procedure is not very complicated even though the description may look lengthy due to the many screenshots. The biggest hurdle is to pick the correct file format when exporting your S/MIME key on your Mac.
The key is to export the certificate in Personal Information Exchange (.p12) format. These can then be imported to iOS.
Outline of the set-up for receiving encrypted emails:
Export your private key in a format that you can import on your iOS devices.
Next, save the certificate in p12 format.
Now drag this exported file to your Mail.app icon to send it to yourself.
Turn to your iOS device to import the certificate.
Enable S/MIME in advanced mail settings and choose your certificate.
Outline of the set-up for sending encrypted emails:
Import the recipient's public key.
Send the email.
What's a bit unfortunate is that there's no easy way to selectively send encrypted emails. The encryption setting is global for the account under 'Settings,' meaning that you have to go there and enable/disable encryption for all messages from that account. It would be nice if that were the default only, with an option to override it in the message composition view.
It would also be nice if public key importing were automatic, like it is on the Mac. But all in all, it's nice to be able to read encrypted emails on iOS devices now.
[crarko adds: To best follow the process, do take a look through the article at the link provided above. There are numerous screen captures on both the Mac and iOS sides which illustrate the procedure exactly, and are far more efficient than trying to translate them into verbiage.]
