Hardware wise the iPad is a whole different “beast” so to speak than the iPhone. The iPad is currently running a custom apple processor called the “A4″ which is a 1GHZ processor that is incredibly fast and significantly faster than the iPhone’s processor. The screen size is obviously much larger than the iPhone at 9.7 inches which makes a huge difference in usability. The iPad also features a 64GB version which is more memory than the iPhone currently holds at 32GB. The iPad much like the iPhone has a version that does allow 3G connectivity however the iPad uses the new Micro SIM card rather than the regular SIM card that the iPhone uses.

Both the iPad and the iPhone feature the same sensors and other hardware such as built-in microphone and speaker however the iPad does not have a vibration unit like the iPhone there it will only produce sound with alerts and not vibrate. The iPad weighs 1.5 pounds which will feel heavier in your hand than an iPhone however it is still comfortable to carry.

Software-wise the iPad is running a modified version of the iPhone 3.2 OS which boasts some new features the iPhone does not have in addition to many changes to the user interface. The biggest changes include drop down menus in many applications and split-screen applications such as in the mail application. These changes are to account for the much larger display of the iPad and allow for more usability. The App Store application on the iPad feels a lot more robust and functional than on the iPhone version and closely resembles the desktop counterpart.

Application-wise the iPad can run practically all of the original apps for the iPhone although it does have to scale them which looks slightly unusual on some of the apps. Many developers have released HD versions specifically for the iPad which allow beautiful functionality and appearance on the iPad’s now larger and more beautiful screen. At the center of the iPad and the iPhone is the same design and elegance that comes from Apple and therefore users will notice many differences between the two however they will always be closely related.

teen buzz

The mosquito ringtone, which is a ringtone geared toward especially high frequencies that only young people can hear is really catching on in schools, clubs, or other places where children and teens want to use cell phones surreptitiously. This type of ringtone is also called the “adult proof ringtone” and with good reason.

The range of human hearing starts to fade for most of us around age 20, while teens retain the ability to hear the highest pitch of sound in the normal human range. What this means is that most teens can hear sounds that 90% of adults simply can’t hear at all. Even if adults can perceive the sound, it generally registers as a slight pressure in the head, or as a soft popping noise. Turning this sound into a ringtone means that children and teens can hear phone calls and incoming text messages, without a teacher or parent being aware.

“So what not just put the phone on vibrate?” Some ask, after learning about mosquito ringtones. After all, it seems sort of complicated to assign a non-audible ringtone, when a vibrate function would be just as good. Teens know the answer to this. When vibrate is turned onto a phone, it’s still audible – especially if it has something to vibrate against, like a desk or a book. The beauty of the mosquito ringtone is that it doesn’t vibrate, and can’t be heard at all by anyone who is significantly older.

Still there’s a lot of skepticism about how well these ringtones really work. If a kid can hear it, what about a parent with exceptional hearing?

The truth is that up to 90% of adults can’t hear sounds between 18-20 khz, while up to 70% of those younger than the age of 17 can. This means that there are very good odds of ensuring that a mosquito ringtone audible to a teen won’t be heard by an adult. Of course, there will always be some rare exceptions, but there’s a good chance that someone using a mosquito ringtone will be able to use it in secret.

The beauty of a ringtone that adults can hear is also that they are not expecting it. When adults can hear a high pitched frequency, they often assume it’s due to fluorescent lighting, or to an old TV or computer monitor. These kinds of monitors did once emit high pitched noises, before largely being phased out in favor of flat panel LCDs. This means that even if an adult can hear a mosquito ringtone, they will have a very hard time determining its origin, or knowing that it’s coming from a cellular phone. This gives children and teens a huge advantage.

So do mosquito ringtones work? They absolutely do. Still, it’s a good idea to test out a range of pitches and frequencies to ensure that the tones you can hear are really inaudible to the older people around you.

The App:
It’s a single screen app that has all the options on it including a slider to adjust the frequency of the “Whistle” and a bark detector! If you enjoy playing around with mosquito ringtones and seeing who can hear what, it’s worth it to be able to change the frequencies quickly.

It didn’t quite work for me with my dogs though, but I have’t had a lot of time to spend fine tunning the frequency yet. I did notice that when I played some of the frequencies that correspond to our free ringtones of the same frequency, my kids where unable to hear them as the normally do on my website. Either the frequencies are off or it’s getting changed/modified somehow. I hope to have time soon to fine tune it for my dog and see if it is a viable replacement for a dog whistle.
