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.]
Maybe everybody already knows this, but I missed it in all the new features of iOS 5. The iPad mail app adds a new gesture to show and hide the message list window when in portrait orientation.
I always use my iPad's Mail app in landscape mode because I get to see my message list in addition to the message detail. And for some reason, I find it tedious to push the mailbox button at the top left of the screen to see the message list. iOS 5 added the ability to swipe right anywhere on the message window to pop up the message list and to swipe left to hide it again. Nice! Not having to move my finger six inches has somehow made portrait mode much more bearable for me.
[crarko adds: Well, I didn't know it either, so here's the hint. I also was a landscape mode only iPad mail user.]
As you know, there are plenty of tools to keep track of shipments that are shipped with UPS. There is an app called Delivery Status which even recognizes an UPS shipment by just copy and pasting the tracking number into the app.
I just noticed that iOS seems to recognize the shipment all by itself.
In iOS Mail (iOS 5.0.1) every number is highlighted to be called as a possible phone number. But in this case the number was my UPS tracking code. Upon tapping the number I got the options to either copy it or track it.
By tapping tracking it opens an ups site with the tracking number already applied to the script so that you can see the status of your shipment. Ergo no need to copy and paste an UPS tracking code to any other program or the UPS site itself.
[crarko adds: I tested this, and it works as described. As mentioned in this previous hint this was a new feature in Mail with Lion. This hint confirms it for iOS 5 Mail as well.]
On a French system, one cannot edit Game Center settings (country, emails, and more importantly, confidentiality -- if your profile is public, you can't switch it to private).
Steps to Reproduce:
Setup iOS in French.
Go to Game Center.
Touch the mail address (it has to be already configured).
Choose to view the account.
Try using one of the following actions:
change email address
Additional note : there is no Save button on the upper right corner.
A solution to perform changes is to switch the system to English and when done, switch it back to French.
[crarko adds: I haven't tested this one. I presume this affects other non-English language localizations as well, and they would use the same workaround, until Apple improves on international support for Game Center.]
In the latest version of Safari for iOS, pressing and holding the add tab [+] button will show a list of recently closed tabs. Touching one of the listed pages will open it in a new tab.
[crarko adds: I tested this, and it works as described, although it seems a bit inconsistent in how it handles the list. Closing Safari with no open tabs clears the list, but if there are tabs still open the list is maintained. Actually quitting Safari (clicking the 'X' in the multitasking bar) clears the list whether there are tabs still open or not.
Note: As mentioned in several of the comments, this only works on an iPad.]
I'm using the iPad 2's 10 Watt wall charger and wireless sync, and it works very well. The only thing that kept bothering me was how to tell how much the battery was charged without unplugging it.
Here's how: If you have the iPad's screen locked, press and hold the Home button. After a few seconds the battery charge percentage will show up next to the 'Charging' icon in the top right of the screen.
[crarko adds: I tried this with a first-generation iPad and it did nothing. However, going to Settings » General » Usage and turning on the 'Battery Percentage' slider makes the charging level always visible. Does the iPad 2 behave differently?]
There is no easy way to mass delete some (but not all) photos from the Camera Roll from the iPhone. Here is the solution I found.
Before iOS5, I'd never used the iTunes app to sync my photos. Instead, I've used the highly rated app called PhotoSync (wireless sync for iPhoto/iPhone). When doing this, my iPhone collected many photos, all 1561 of them and never deleted them. The solution was to mount the iPhone as a camera in Apple's Image Capture application. This allowed me to select my 1000 photos I didn't want and delete them with ease.
[crarko adds: Once again, Image Capture comes to the rescue. Note that iPhoto will either let you keep or delete all the images on an import, but doesn't give much choice beyond that.]
