WikiPock – Wikipedia in your pocket
WikiPock is a utility for Windows Mobile devices and Blackberrys, that lets you search Wikipedia without being connected to a network. The costs for this convenience is quite reasonable. The Basic version is $9.99 and the Plus Version, which includes updates for a year and two additional databases, is $14.99. The additional databases are Wikiquote, and Wiktionary. The wikipedia database is currently 5 gig in size. If you don’t have that much free space and you need to buy a memory card, they sell an 8 gig microSDHC card with the database preloaded for an additional $15.00. The database includes full editorial content except images.
I have found it quite useful and a battery saver. I find I use it every day. You can read all about it here: http://www.wikipock.com
The search is real time displaying matches as you type. Here are some screen shots showing the Search page and the results after searching for HTC t and then clicking on HTC Touch Pro:
