Henry, CKCHNG, so sorry but the iPhone version will not be avail anytime soon... After I read through the development guide for iPhone, just found out I need a Mac to develop iPhone apps...
New feature include the following:
* more photos with new contributor (still adding)
* revised write-up (work still in progress)
* GPS tagging output to Google Earth file format - double click the file in Desktop PC will open Google Earth & show the Placemark directly.
