You can rename folders in Finder window sidebars from a contextual menu. This also renames the folder that it links to, so use with caution. You can also drag a folder from the Finder sidebar to the Dock.
[kirkmc adds: This isn't new; renaming goes back at least to 10.6, but you can't drag a folder from the Finder sidebar to the Dock until 10.7. Nevertheless, it's not on the site, so it's worth mentioning]
I was recently stymied by my iPhone 3GS that refused to launch any third-party apps. I would open an app, the start screen of that app would flash, and then I would be dropped back to the home screen as if the app crashed.
Due to extenuating circumstances, I was unable to restore from a backup. Also, I wasn't at my usual computer that manages my iPhone, so there was the fear that I would lose all my non-iTunes Store acquired music, apps, etc. And to top it all off, iCloud restoration was not an option as I'm still running iOS 4.x.
Before I stumbled on the solution, I believed the only option available to me was to wipe my phone and reload iOS from scratch.
You can try the following steps to restore launching of third-party apps:
1. Download any free app to your iOS device (you can delete it later). Third-party apps should now open. If not, continue with the following:
2. Connect your iOS device to a Mac or PC with an empty iTunes library on it (if necessary, use option when opening iTunes to force a new library location, or create a new user account with an empty library).
If you need to restore functionality and you're not at your usual computer, make sure you first go to iTunes preferences, click on Devices and select Prevent iPods, iPhones, and iPads from syncing automatically. Note: Make sure you do not allow iTunes to sync your iOS device to any different copy of iTunes, as you will lose all your iPhone's contacts, notes, apps, music, etc.!
3. In the iTunes source list, right-click your iOS device and select Transfer Purchases from [your device name].
4. Let it transfer all your purchased music and downloaded apps to iTunes. (You may need to sign into iTunes.)
After iTunes transfers your purchases, try to open a third-party app. If it still doesn't work, try opening an app after each step of the following:
5. Right-click your iOS device and select Backup (note that this is different than sync).
6. Reboot your iDevice
Hopefully these steps will save someone a lengthy troubleshooting session to get their apps working! Thanks goes to Alvin Alexander at devdaily.com for providing step 1.
PS: If you perform step 5 on someone else's computer, make sure you use secure delete on the backup files once you've finished. On Macs, the backup is located ~/Library/Application Support/MobileSync/Backup/
and on Windows it's located C:UsersuserAppDataRoamingApple ComputerMobileSyncBackup.
[kirkmc adds: Fortunately, I'm unable to test this, bit it makes sense. It's worth posting in case it might help someone resolve a similar problem. Naturally, the best way to solve this is to simply restore the device, but if, like the poster, the computer than syncs with your iOS device isn't available, this is a good option. Or iCloud backups, if your device is compatible with that feature.]
Does your iPhone constantly defer to 3G or 4G, even when you are standing right next to your Wi-Fi router?
I recently discovered that the two iPhones (a 3GS and a 4S) in my household were both deferring to using 3G and 4G instead of using Wi-Fi. All the other devices (two laptops, one iPad 2, and two Direct TV boxes) were doing just fine.
I looked all through many tutorials online and tried a number of weird tricks and resets and was getting pretty flustered about it. Then I looked into why it would be affecting out phones and not our other devices and found this:
Pre-iPhone 5 models do NOT support the newer 5GHz Wi-Fi spectrum. All the other devices in my house, including the iPad2, DO support the 5GHz Wi-Fi spectrum. This means that the only devices using the 2.4GHz range on my router were the two iPhones.
I logged into my router's control panel to have a look at the 2.4GHz settings. At first I was considering changing its security settings from WPA2 to WPA Enterprise, but first I decide to try something simpler. I changed the 2.4GHz channel setting from "Auto" to a dedicated channel, and everything was back to normal.
I wish I could provide an explanation for why this worked. It seems there are many of people having this issue. I hope this helps you if you are.
[kirkmc adds: It is entirely possible that there was interference from other people's routers on the channel you were using. By changing the channel, you found one that is less encumbered. But this is certainly something to try if you are having Wi-Fi connection problems, and not just with an iPhone
5GHz is not really "new," it's just not been supported by mobile devices for very long. I've had a 5GHz network in my home for a few years, even though, for a long time, only my Macs would connect to it.]
It is now possible to have Find My Friends app send notifications to e-mail addresses.
I like the Find My Friends app, which allows you to see where your friends are located (if they allow you to). With the latest version, in iOS 6, you now have the option to be notified when a friend leaves or arrives at a location.
But you can also set up notifications for yourself, to notify others where you are currently, as well as when you leave or arrive at a location. Additionally, you can send an e-mail automatically when you arrive or leave a location, or send an e-mail showing someone where you are currently
To do this, open Find My Friends, tap Me, then Notify. You can now tap either Immediately, to send an e-mail right away, or At a Location, to send an e-mail when you get to that location. Tap on the To field to enter an e-mail address. If you choose an Apple ID for a friend who has the Find My Friends app, they'll get a notification on their iOS device. But if you enter a different e-mail address - such as one for someone who doesn't have the app, or an iPhone - an e-mail message will be sent. This is nicely formatted, and contains a small map (using Google maps) showing your location.
So if you need to tell someone where you are, and they don't have an iOS device or the Find My Friends app, this e-mail can be a big help.
With iOS 6, you can choose to limit (though not entirely disable) ad tracking, by digging deep into settings. Go to Settings > General > About, then scroll down to the bottom and top on Advertising, then toggle Limit Ad Tracking to On.
There's a tiny Learn More link at the bottom of that screen, which explains that this uses a "non-permanent, non-personal, device identifier, that apps will use to give you more control over advertisers' ability to use tracking methods."
[kirkmc adds: I'm not entirely sure how effective it will be, as it's still in its infancy. But it can't hurt.]
Before Safari 6, you could navigate to a URL with having to type ".com". The same can be done in Safari 6 with one extra keystroke.
Entering "apple" in the location bar of Safari 6 will yield you Google search results for those terms. However, including a trailing slash will cause Safari to add the .com TLD to a logical location in the address, and take you to that URL. So, "apple/" will take you to apple.com.
[kirkmc adds: This is fine, if you're trying to get to .com sites. If you're in a country and want to get to local sites, it won't help you. It's worth noting that you can enter any number of slashes and still get this to work.]
Update: As per a comment below, here's how to make it work when you type a /. For example, if you type "apple/ipod/" Safari will go to www.apple.com/ipod, if you do the following. Go to System Preferences > Network, click on Advanced, then DNS. In the Search Domains section, click on + and add .com. Click on OK, then on Apply.
