Wi-Fi is the latest cutting edge technology to come to mobile phones. In the past, web browsing on phones was not popular because of the high cost and slow speeds. Nowadays since PDA phones are becoming more and more like computers, Wi-Fi has been added to the list of features.

With Wi-Fi you can not only access the internet at high speeds, you don't need to worry about high internet rates. Virtually everywhere you go now there is a wireless signal. With Wi-Fi on your PDA you don't need to carry your laptop everywhere you go.  Some cellular devices that are equipped with Wi-Fi include the T-Mobile MDA, Samsung SCH-i730, and HTC P3300.
