Can I use any of the iPAQ Pocket PC h4700 models as a phone?
A . No, the iPAQ hx4700 series Pocket PC models have integrated wireless LAN technology, which requires an 802.11b infrastructure in place for connectivity. Therefore, this device is intended for data use, as opposed to voice communications. The exception to this might be the use of a separately purchased Voice Over IP software application, which allows you to use this device as a VoIP phone in an 802.11b WLAN environment.
