Basic History and features of the iPhone

First off, the very popular iPhone is now plugging their most recent incarnation of phone which is the iPhone4. The first iPhone was released in 2007, only about 4 years ago. The basic features of the iPhone:

• •voice calls
• •text message
• •still camera
• •video camera
• •media player
• •email
• •web browser
• •multi-touch navigation screen
• •Wi-fi and 3G connectivity
• •2 (front and rear facing) cameras

There are presently close to 90 million iPhones sold (all versions included)!! That is quite an accomplishment!
The capacitive touchscreen’s resolution of the iPhone4 is 640 x 960 at 326 ppi. Why is it important to know about the type of touchscreen that a smart phone uses? Well the type the iPhone uses relies on the fact that human bodies conduct electricity. If you happen to be wearing gloves, the iPhone won’t respond. If you’re saying, “who cares” to yourself right now, you’ve obviously never been outside waiting for a bus in 10°F weather and had your phone ring. Taking off your gloves in this weather just to answer your phone is not to be taken lightly!

The iPhone does not natively support the transferring of files (pictures, video etc.) by Bluetooth (OBEX file transfer protocol). For some strange reason (just like the ipod), the iPhone does NOT allow the user to replace the rechargeable battery. This has always been an odd “feature” oversight for Apple.
