Geooh gives you powerful ways to geocache without having a cell network. First, downloading Pocket Queries, GPX files, and Bookmark Lists will retrieve all the necessary geocache information so that you can review cache details and logs without using the cell phone network. For searches, be sure to uncheck the Lite Download option so you will include detailed information in the search. Although the search will take longer, it will reduce the need to access the network later.
For posting logs or other geocache tasks that communicate with geocaching.com, Geooh will store the task data in a saved queue if the network is not available. Then later when you have cell access, you can look at a list of the queued tasks and submit them individually or in a batch. You never have to worry about not having network access again while geocaching! :D
