We previously reported that the second-generation jailbroken iPod Touch required either a hardware dongle or a computer to be booted.

Recently, the iPhone development community has resolved this inconvenient booting method by releasing a software-only jailbreak solution. As a result, the current software/firmware 2.2.1 revision has been jailbroken (full read/write access to the file system), meaning that unofficial third-party applications can be installed under this release.

According to a post on ipodtouchfans.com, this exploit had been discovered "shortly after redsn0w in early February," which means the discovery was made sometime after the initial (… Read more

Exploding batteries make headlines, but they're just the tip of the iceberg. If you've read owner's manuals, as I do, you see danger lurking everywhere. A couple examples:

"When not using remote controls, remove batteries. Do not take battery apart, heat it, or throw into fire." Curious kids do that kind of stuff all the time (I did), and the fine print in the owner's manual won't deter them. I suppose that the warnings are in there for legal reasons.

"Do not subject remote control to undue physical stress, such as striking it or dropping it." Wow, who would have thought that by merely dropping a remote, you're at risk. I guess that those of us with bare wood or tiled floors are living dangerously. Heed all warnings!

I haven't yet seen the next warnings in any manual, but it's just a matter of time before they appear.

"Do not put the battery in your mouth or swallow it." That's just common sense, but the tingling sensation of a few volts zapping your insides may...don't do it!

"Do not sit on batteries, and if you do, be aware that flatulence may pose additional risks." Of course.… Read more

Not everyone cares about audio quality. In fact, there's some evidence to suggest we're raising a generation that actually prefers the sound of MP3s over higher-fidelity recordings. Still, there will always be people who obsess over sound quality--just as there are always people with discerning taste in food, or an eye for fine art.

There was a time when fidelity fanatics wouldn't touch an iPod with a 10-foot pole, and clung tightly to formats like vinyl, CD, and SACD. Things have eased up over the years, though, as the devout have begrudgingly come to terms with the … Read more

The Audiophiliac's primary mission is turning readers on to high-quality audio products and great music, but today, it's more about super lo-fi.

Google's YouTube has loads of wacky videos on how to make cheap speakers. Check out my favorite so far, "How to Create a High-Def Speaker for Under a Buck," right. It doesn't work, but it's the most entertaining.

After that, watch "Attempting to Make a Homemade Speaker for Under a Buck." It's a response to that first one.

If you really want to give speaker building a try, … Read more

Most new AV receivers come with an "auto setup" or "automatic calibration" feature, but despite the word automatic, these features can stump AV novices. If you're setting up an AV receiver for the first time, this guide will put you on the right track.

First, let's describe what auto setup systems do.

They send test tones to all the speakers and subwoofer, and use a microphone to pick up the sound of the speakers in your room. Auto setup systems determine speaker sizes and volume levels, set the subwoofer-to-satellite crossover frequency, measure distances from each of the speakers to the listener, and confirm that all of the speaker cables are correctly hooked up. Some receivers also use equalization to balance the frequency response of all the speakers.

Auto setup systems go by different names, but they all do approximately the same thing. Denon and Onkyo feature Audyssey; Sony has Digital Cinema Auto Calibration, Pioneer Multi Channel Acoustic Calibration, and Yamaha uses a Parametric Room Acoustic Optimizer.

The exact positioning of the auto calibration microphone is crucial for achieving accurate results. Some auto setup systems work from just one mic position, which would be the primary spot where you sit when watching movies by yourself. Ideally the mic should be placed at the same height as your ears when you're sitting watching a movie.

If you have a camera tripod, use it to place the mic at ear height; perfectionists should move the couch entirely out of the way. Lacking a tripod place the mic on the back of the couch, atop the highest pillow.… Read more

I love in-ear headphones--the ones that fit inside your ear canals, as opposed to ear buds that rest on the outer ear. I'm a big fan because in-ear headphones' ultraclose proximity to eardrums offers the potential for the highest-resolution sound quality.

The better in-ear headphones also do a great job of sealing out external environmental noise so you can listen at a lower (safer) volume and still hear all of that amazing detail. The problem is, unless both earpieces are sealed tight, you're not going to get the sound you paid for.

Everybody's ears are different, so achieving a perfect fit can be a tricky exercise. Most in-ear headphones come with a selection of differently sized and shaped eartips. Try them all; the goal is to produce a the best possible "seal," which reduces the amount of outside noise you hear and delivers the headphone's fullest-possible bass response.

The difference in sound quality between a good seal and an iffy one isn't subtle. It's definitely worth a little extra effort to maximize each tip's seal. Remember, too, that poor sealing makes for a less secure fit, so the earpiece is more likely to fall out of your ear.

Tip: Your left and right ear canals may not be exactly the same size; you might need, for example, the smallest eartip for your right ear and a medium tip for the left ear.

I've included a gallery of images to help perfect your in-ear insertion techniques. First, try rotating/twisting the tip slightly as you push the headphone inside the canal. … Read more

Our friends across the pond at The Register are reporting about an issue that has been discovered surrounding Apple's much touted MobileMe trial especially when trying it for the limited time period and then canceling it.

Synchronization with MobileMe makes sure that all the devices are up-to-date regarding content, etc. However, something really bad happens "when an account is canceled; all the data is removed from the cloud, which is fine - unless the user lets their iPhone synchronize with the newly-created void. In that case they find their calendar unexpectedly clear, and a curious lack of any … Read more

Travel woes during winter are not new - canceled flights, delays, missed connections, you name it, it's likely to happen. Being stranded at a hub airport is probably the last thing you wanted to happen. Boy, that airport floor is a might comfortable bed, right? What's worse, if you're delayed you tend to have to wait in monstrously long customer 'service' lines to find out what your fate is. What's even worse is finding out that you missed an alternative connection while you were waiting in line!

The situation has gotten worse as the airlines cut … Read more

If you've read my iPhone Apps of the Week posts, you know that I mostly download games and entertainment applications. I also like to check out music apps, because I play a few instruments and am continually interested in what developers are able to come up with musically for the iPhone. Since my coworker, Jessica Dolcourt, wrote the iPhone Starter Kit based around must-have apps of the practical variety, I can really get down to business--the business of fun iPhone apps!

So, what makes a great game or music app? Certainly graphics and sound are important for games, but with a platform as unique as the iPhone or iPod Touch, it's important to consider how it utilizes the accelerometer, touch screen, and other aspects of the device. For musical instruments and drum machines, it's important to note whether the sounds are realistic and how intuitive it is to play the instrument. Finally, it's important to note whether a game or instrument is a good fit for the medium. You probably wouldn't want to spend hours playing an MMO on a tiny device that needs recharging, and, similarly, you're probably not going to be writing concertos on your iPhone. The point is that it should be a good app by itself in addition to being a good app for the iPhone.

Some of the apps I'm including for this end-of-the-year roundup have been in previous posts, but several are new apps to my iPhone. I'm including both free apps and apps for purchase, and sometimes I have a good free version of a genre you can try if you don't want to spend the money. Without further ado, read on to see my favorite fun apps for the iPhone and iPod Touch.… Read more
