Solution: Put executable (less than 1 megabyte) in main BlackBerry memory, while putting map data (gigabytes) on the memory card. Instead of using a small temporary map cache in main memory, use a large permanent map cache on the memory card instead (holding entire North America) and sell this data at $100 per year.

Ok, that still good but still limited of what you can install onto the BB. And thank for the tip about selling those data for the $100. Maybe I can get something out of this.
Back to SD. I noticed accessing a video file, it is not as fast? Is this true? Meaning, when I watch a video clip on the BB, it having trouble syncing the video with the audio. At first, I thought it was just the conversion process that maybe the cause of it. But when transfer back to the PC, it played just fine. So what I am assuming is, the SD is abit slower of reading a large file? The reason I use Video as an example because I don't really know yet about how good if data map can be retrieve on the SD.
Currently I don't know of any good map vendor like MQ and TeleNav to be installed onto the SD and no OTA. OTA have problem at certain area that do not have service but your signal (EDGE) is good. I brought this example up because of a case that had happen from Google Map, Yahoo and BBmap. I tried to find direction from Moraga California (St Mary's College compus) to a distination and my BB indicating there no service to download the direction I request. I looked at my BB for signal bar and EDGE, it all there and strong but no service from the map data server. As soon as I got out of the campus and tried again, it work just fine. I am curious if there any Map vendor out that do not have OTA for BB but can be installed to the SD.
