iOS 6.0.2 Released with Wi-Fi Fix for iPhone 5 & iPad Mini

Apple has released iOS 6.0.2, a minor version release with a major fix aimed at iPhone 5 and iPad Mini users who have experienced problematic wi-fi connections with the devices. The changelog for the 6.0.2 update says the update includes improvements and bug fixes, but only lists "Fixes a bug that could impact Wi-Fi" in the list of adjustments.

The iOS 6.0.2 update is available now and can be downloaded from iTunes by connecting the iOS device to a computer, updated with Over-the-Air from the device itself, or by directly grabbing firmware files that are hosted by Apple and updating manually with IPSW. Attempting the OTA update may provoke a temporary error as the release propagates throughout Apple's content delivery servers, if you encounter such an error try again in another few minutes. The OTA update is by far the quickest method and the smallest download, taking less than a minute to install.

These are direct download links of IPSW files hosted with Apple, right-click and choose "Save As".

• iPhone 5 GSM
• iPhone 5 CDMA
• iPad Mini Wi-Fi
• iPad Mini LTE GSM
• iPad Mini LTE CDMA

We've discussed various connectivity and wi-fi issues pertaining to iPhone 5 on separate occasions, and previously offered a workaround that involved setting manual DNS entries which provided some relief for the sporadic wireless speed issue. Making troubleshooting initially difficult was the observation that wi-fi problems only manifested when a particular iOS device was connected to certain brands or models of wireless routers. The iOS 6.0.2 update is expected to resolve this entirely, regardless of the router or device in use.

As of now, the iOS 6.0.2 update is limited to iPhone 5 and iPad Mini. For other users, iOS 6.1 is currently in beta and expected to be released within the coming weeks.

Save Pictures from Facebook to iPhone & iPad the Easy Way

The easiest way to save a picture from Facebook on an iPhone or iPad is to:

• Open the image you want to save, then tap and hold on that image and select "Save Photo"

Now look in the Photos app to find your saved picture. Easy right?

Before Facebook had the Save Photo feature, you had to manually zoom in on a picture, then take a screen shot in iOS, and that screenshot would be the saved picture – that was a totally lame solution but thankfully it's no longer needed if you're in a more recent version of iOS and have an updated Facebook app.

Well, at least, that's how it's supposed to work, but recently there have been some issues…

Fixing Problems with Facebook Unable to Upload & Save Pictures to iPhone & iPad

If you've tried to save a photo from the Facebook app recently on your iPhone, iPad, or iPod touch, you may have discovered that despite tapping "Save Image" as usual like you would to save a pic from the web or Mail, but when you flip over to the Photos app, the picture doesn't actually show up in the photo library or Camera Roll. Likewise, many have encountered a giant Lock screen when trying to upload a photo to Facebook, rather than your typical photo collection.

Both of these issues are due to a privacy adjustment with the latest version of iOS, and they're both very easy to fix:

• Open the "Settings" app and tap on "Privacy"
• Choose "Photos" and locate "Facebook" to flip the switch to ON
• Tap back on "Privacy" and now locate "Facebook" in the app list, check to make sure Facebook has access here as well by flipping to ON

Exit out of Settings and return to the Facebook app to have full photo access again, both for saving and for uploading pictures.

As mentioned, these privacy options are due to the recent iOS 6 update and shouldn't impact anyone who downloaded the Facebook app after updating to iOS 6 or on any device that was pre-installed with iOS 6 or later, like iPhone 5 and new iPads.

Reset App Access to OS X Privacy Data from the Command Line

If you accidentally permitted an app to gain access to things like your personal contacts list or location, or you'd just like to start over again and have granular control over which applications can access certain data, you can use the command line tool tccutil in OS X 10.8 and later.

Think of the tccutil command as a kind of command line interface to the Security & Privacy control panel, which let's you control apps access to things like contacts, location services, usage statics, and more. This is separate from GateKeeper, which controls the ability of certain applications to launch.

Most users will be better off using the friendlier preference panel, but for those who like to tweak things from the Terminal, here's the basics of tccutil command:

At it's core, tccutil is used to manage the privacy database like so:

tccutil reset [service name]

The example given in the tccutil man page resets the privacy database for which apps can access the Address Book (Contacts) like so:

tccutil reset AddressBook

This will revoke all applications access to AddressBook, meaning the next time you attempt to open any application which wants to access the contacts information, you will be prompted to either allow or deny access for that specific application. That process will repeat itself for each additional app who attempts to access such data.

Similarly, you could apply the same reset to Location Services with the following command:

tccutil reset CoreLocationAgent

The same applies here, all apps that have access to Location Services will be removed, requiring a confirmation again in the future.

You can find a detailed list of services – not all of which will be relevant to tccutil – by entering "launchctl list" into the terminal. As mentioned at the beginning of the article however, if you don't know what you're doing here and why, it's best to stick to the Privacy preference panel to control this type of personal data access.
