A work in progress as of 2-07 Do you need a data plan to use GPS?
Yes for now. Rumor is that there are programs in the works to utilize the microSD cards on the 8100 and the 8800 to come. Why do you need data? To get the maps that are downloaded OTA. What do the GPS programs do?
Most of them are driving direction programs. There is one that is for geocaching.
What do the GPS programs facilitate?
Most of them are GUI's to various data providers. They provide a graphical user interface to the data - the maps, and the points of interests. Some do this much better than others.
What broswer do you need to use to get BBMaps?
You need the use the one labeled Blackberry Browser, not Internet Browser or a third party browser like Opera Mini. What areas does BBMaps cover?
Originally the US and Canada, but in Jan 07 the UK was added. If Google Maps isn't connecting, what should I do?
