It's one of those essential upgrades I never get tired of. iSilo (http://www.isilo.com/download/index.htm), still my favorite e-book reader for Palm and Pocket PC, has been upgraded to V4.29. The upgrade includes the following improvements and fixes:


Added content read caching for all platforms except for Palm OS platform, which already had it. Improves slow reading of large documents on Symbian OS platforms.
Addressing of miscellaneous issues (such as improved WM 5.0 support for Dell Axim devices)

iSiloX (http://www.isilox.com/download/index.htm), the desktop companion, has also been upgraded:


Added recognition of application/xhtml+xml and .xhtml/.xhtm as HTML extensions.
Addressing of miscellaneous issues.
