Phones!!!

. Group Communication If you find yourself working on a group project or needing the advice of a few friends as you do your history homework, try using the three-way calling feature. It's available on most cell phones.
You may not even be aware that this feature is available on your phone, so you may want to experiment a little. First call one friend and establish a clear connection. Then enter the number of a second friend on the keypad and press send. If your phone has the three-way feature, then the second call will go through and the first friend will be on hold. Simply press send again to re-connect with the first friend.
Cell Phone as Audio Tool Some cell phones come equipped with a voice recorder. This tool can be priceless if you tend to forget things. You can use the recorder to remember homework assignments, to memorize terms, to practice foreign language pronunciation, and dozens of other tasks. It's a great feature for auditory learners.
If your phone doesn't have the voice recording feature, you can accomplish many of the same tasks by sending yourself a voice message.
Pictures and Illustrations More and more phones come equipped with picture-sharing features. This is important because pictures can be used as illustrations in reports and presentations. If you're in the library or out and about and you see an image that would work for a project, simply capture the image on your phone.
The are several ways you may be able to save and transfer the picture. Depending on the cell phone, you may be able to use a memory card, Bluetooth technology, or a USB cable that connects your cell phone with your computer. You may have to do a little detective work to find the best method for your phone.
Podcasts Right now it's pretty expensive and cumbersome to access a podcast from most cell phones, since many cell phones require the middle step of downloading a podcast to a computer. But technology is barreling along pretty quickly. With the advent of cell phone/MP3 player combos, the prospect of widespread podcast sharing is growing ever more likely. Look for teachers/professors sending podcasts and students accessing them more and more.
Sending Money There may be times when you need to travel to conduct research or to visit prospective colleges. Parents may be interested to know that your cell phone can provide some security while you’re on the road.
