Apart from music and videos, one of the things for which most use the mobile library is as portable, above all in order to see things anywhere. MobiCHM is the first viewer of help files compiled in CHM format for Symbian phones, files very common in systems with Windows or Windows Mobile.
MobiCHM allowed to consult the index or the contents of the file, search or add bookmarks. The screen can be rotated to landscape mode for easy reading and supports HTML codes that typically compose such files.
The program costs 20 U.S. dollars and can try a demo version, somewhat limited in any mobile Symbian S60 3 edition.
