Palm’s latest PDA phone, the 700p, harnesses the 3G power of EV-DO cellular broadband to give 
you high performance voice and data communications in the field.
EV-DO or EVolution - Data Only is protocol implemented on CDMA (Code Division Multiple Access) cellular networks. In the U.S., that’s Sprint and Verizon Wireless. EV-DO redeploys some cellular channels to transmit data rather than voice. In particular, Internet data. How fast is EV-DO? Sprint estimates up to 700 Kbps downloads, although burst speeds can be higher. Beyond the range of EV-DO coverage in major population areas, the system gracefully falls back to an earlier standard called 1xRTT that supports downloads up to 130 Kbps.
For a handheld device with a relatively small screen like the Palm Treo 700p, downloads at 700 Kbps can easily support streaming audio and video, mobile Web browsing, and email packed with attachments. Sprint also offers aircards for your laptop PCs so you can get Internet broadband out of the office. Palm Treo 700p 3G smartphone
