Turn your iOS device into a killer Craigslist companion

I'm a bit of a Craigslist junkie. I've used it to buy everything from a piano to a loft bed to a go-kart, and to sell or give away a host of unwanted items.

But despite its spartan interface--or perhaps because of it--the service isn't particularly user-friendly. For one thing, it doesn't let me save individual listings. And adding photos to my own listing means copying them over from my camera, resizing them, and on and on. Hassle city.

That's why I'm jazzed about apps like Lifelike Craig HD, which can turn an iPhone, … Read more

Share your GPS location without compromising your privacy

There are plenty of location-sharing apps such as Foursquare, Latitude, and Gowalla that allow you to share your location with your friends, but these apps require that both parties be signed up and using the service in order to work. Many people simply aren't keen on having an app like Google Latitude watching their comings and goings. For those times where you need to let someone know where your are, I'm going to show you how to share your GPS coordinates with your friends or family members without compromising your privacy or theirs using little more than your … Read more

Make your own ringtones on Android, iPhone (video)

Cutting your own ringtones from songs in your mobile library isn't hard at all, and there's even one ingenious Android app that takes a much more creative approach than the usual slice-and-serve.

iPhone apps also handily make ringtones. Apart from choosing the start and stop times--which can be frustrating and time-consuming depending on your level of meticulousness--the most trying portion of the creation process is transferring your newly created selection to iTunes and then back to your computer as a ringtone.

No, it doesn't make sense, but the apps show you how to do it and ultimately … Read more

Jailbreak for iOS 4.3.1 arrives, except for iPad 2

The cat-and-mouse game between Apple and the iOS hacking community is still afoot, with the recent release of an update to a tool that allows users to gain low-level system access and install unapproved third-party applications on iOS devices.

The iPhone Dev Team (not to be confused with Apple's own team that develops iOS), has released the latest version of its PwnageTool and RedSn0w tools, both of which let people jailbreak their iOS devices. The big news with this one is that it's "untethered," which means people don't have to worry about having to re-do … Read more

Apple AirPlay: 10 things you need to know

At some point you've probably heard about AirPlay, a wireless streaming feature found on your iPhone, iPad, iPod Touch, or any Mac or Windows PC running iTunes. While some features had been available for years under the AirTunes moniker, Apple rolled out the AirPlay name and an expanded feature list in the fall of 2010. With the arrival of iOS 4.3, AirPlay has been further enhanced, and--perhaps most significantly--third-party consumer electronics manufacturers are adding it to their products.

Apple sums up the technology like this on its regularly updated "Using AirPlay" page, which has some troubleshooting tips.

With AirPlay, you can wirelessly stream videos, music, and photos from your iPhone, iPad, or iPod touch to Apple TV (2nd generation) and stream music to AirPlay speakers or receivers, including AirPort Express. You can also wirelessly stream videos and music from your computer to Apple TV (2nd generation) and stream music to AirPlay speakers or receivers, including AirPort Express.

That pretty much tells you what it's all about, but here's a closer look at what you need to know about AirPlay and some tips for getting the most out of it.

Only a limited number of products are currently AirPlay-compatible: Right now, only a handful of products offer AirPlay compatibility (see slideshow, below) and they tend to be fairly expensive. The exception is the Apple TV, which only costs $99, and Apple's AirPort Express (also $99 list). The majority of early AirPlay products are speaker systems, plus a few AV receivers that offer built-in AirPlay support.

Back up your data before April Fools' Day

Hello, world! Today it's your Backup Day. World Backup Day is a new idea promoted by a small team of Redditors, and it's a good idea. You can never be too careful when it comes to backing up.

By the way, this is about your data, and not calling your buddies over for help in a hostile situation, which is not really my area of expertise. So let's talk backups!

Basically it means putting your data in multiple places so that if something happens to one place (let's say you forget your laptop on the top of your car and subsequently back over it), that important PowerPoint presentation you've been working on isn't lost.

Backing up is much easier than you might think. For example, if you've been working on an important essay, you can just e-mail it once in a while to your mom or to yourself. Just make sure you use an online free e-mail service, such as Gmail, Yahoo Mail, Hotmail, or all of them. This goes for photos as well. If you remember to e-mail them to your mom when you have new ones (and she'll probably appreciate that very much), chances are she'll save them for you on her computer, and even if not, they are still in the Sent Items folder of your online e-mail account in case you have lost the originals.

Obviously, e-mailing can only handle a relatively small amount of data and you'll have to remember to do that manually. If you have many files that need backing up, you'll want something more robust. This is when a backup plan is necessary.

Online backup Similar to e-mailing, an online backup plan provides you with a certain amount of storage space that you can access over the Internet, aka "the cloud." And no, your data is not flying in the sky, it's stored and managed on one or multiple servers located in different parts of the world. There are many online backup services, such as Amazon S3, McAfee, Mozy, or even Comcast. … Read more

11 iPhone tips for total novices

My very own mom just joined the ranks of iPhone owners. (Welcome to the party, Mom!) Much as I was excited to show her all the cool stuff (FaceTime! Apps! Visual voice mail!), I quickly realized she needed to walk before she could run.

In other words, she needed a course in Basic iPhone Operation. After all, she was accustomed to a simple flip phone with a physical keypad. Going from that to an iPhone is like trading a car for a 747: confusing, intimidating, and no doubt a little scary.

With that in mind, I put together this list of 11 tips for iPhone newcomers. If they seem overly obvious to you, well, you're not the target audience. But I'll bet you know someone who is, so feel free to share this with the iPhone newbies in your life. Trust me: they'll thank you!

1. When in doubt, go Home. Want to go back to the main screen, the one with all the icons? That's called the Home screen. It doesn't matter which app you're using or task you're performing--a single press of the Home button (the only physical button on the front of the iPhone) will return you to the Home screen.

2. Always turn your iPhone off before you slip it into your pocket.Although your iPhone will switch itself into idle mode (where the screen turns off but the phone stays on) after a designated period of inactivity, you should get in the habit of manually turning off the screen. Otherwise you might accidentally place a call or run a battery-draining app while slipping the phone into your pocket. So remember: when you're done using your iPhone, press the top button (aka, the Sleep/Wake button).… Read more

How to download e-books from your local library

Before you purchase e-books from vendors like Amazon or from the iBookstore, see what your local library has to offer. With a library card and a free application, Overdrive Media Console, you can download free e-books and audiobooks to your iPhone (and any other iOS device), BlackBerry, Android device, or computer.

Remember, though, that most libraries might only carry a few copies of each title, so be ready to wait your turn. Additionally, most books have a loaning period of 7 to 14 days, so there's no room for procrastinating here.
