I am in the process of doing a research paper on the MPx200 and thought that some of the information I have found would be useful. The standby time is, I believe 100 hours and the talk time is 4 hours. It is good for about 2 days use, before needing to charge. The phone will not be available until October in England and possibly not until the first quarter in America. I am not sure if all of my information is accurate, but I know what I have read.
2004 february comes V710/720, where is Smartphone edition 2003, bluetooth, integrated camera and different design!!!I cant wait it!
