It looks like the Samsung i700 will be getting a Windows Mobile 2003 upgrade fairly soon. Without much fanfare, a blurb appeard on Samsung's developer's web site mentioning a coming upgrade.
The blurb reads as follows, "An update to Windows Mobile Pocket PC Phone Edition 2003 will be available at Verizon Wireless retail store locations in early 2004."
Samsung originally released the i700 with Pocket PC Phone Edition 2002.
