If your primary interested in the contents of the Web Viewer so you can scape them, is Insert From URL out of the question? I haven't found any differences in the characters from Insert From URL between Mac and iOS. Also, a lot of the useful data in the Google Maps API is accessible via separate XML and JSON web services without having to pull an entire map.
Hmmm... will have to give that a try and see which way InsertURL behaves and if it is displayable on the iOS. The solution is not just web scraping, but also the visual aspects of seeing the map and choosing the icon letter to select the Lat/Long and web scrape the value.
