Downloaded the new version and running tests. Settings are Zoom 14, download batch setting 5 up/5down (so 9-19 is the end result).

Applause: The check feature definitely runs faster, and the total tiles needed is faster. Everything is faster. ALOT faster. Kudos. After telling it to get a 10 zoom level 20+KM range before it would take a long time to even show the download screen with the number of tiles needed. It now only takes about 5 seconds. The check runs a lot faster, too, as in it actually shows its progression real-time rather than freezing the phone for 20 minutes before causing a reboot.

Feedback:
However the Check feature may not be working quite right. Here what i have found so far.
1) Still shows KM and not miles in download area. Not sure if that was one of the fixes mentioned in the change log, but it seemed to be.

2) If you run a check for a given area (ie: 5km, 10km, etc.) and all tiles are considered available, if you just hit "edit" and increase the size and check again it will continue to report that all tiles are available no matter how high you go.

3) if you hit Download anyway, despite #2 above, because you know you don't actually have them, it will finish without having downloaded anything (as noted by the lack of change in disk space) and tell you that all are now available. if you then return to the map and scroll to an area where you know you don't actually have tiles you will just get a black area, and the menu buttons disappear, and the program becomes unresponsive (or rather, unuseable since three are no buttons and the screen can no longer be scrolled) and has to be closed.

4) After restarting the app: going to batch and starting a download for the area you tried to download in #2, it will run normal and start downloading all the missing tiles. However, if i wanted to check the size of the download before letting it continue, to see if it would actually see that i didn't have them, i hit stop and then check. It said i would only need 1.8mb of files, so i hit continue download. As opposed to the slow pace at which it was going before (reporting 2-4 tiles downloaded per second), it was showing thousands downloaded per second (the same speed as the check) and finished without downloading anything. repeat the black screen from #3.

Repeating #4, but this time not running any checks, just letting it download and it is working so far as i can tell. Disk space is going down and my GPRS data counter is moving. So far i am up to 1400 of 371,759 tiles down,space used ~2mb. Should be ~500MB downloaded when finished based on that, which sounds about right. This is a 20KM area i am grabbing of dense city.

Conjecture: The checking and being done and thiking it does not need to download tiles may be an anomoly to me, as the data base may have been marked as downloaded them all when i tried to do it with the last version, even though it had frozen and didn't finish. Or something to that effect. After i finished my current download of my city, i will move to another area that i know i won't have any tiles for and i will try the exact same steps i have done above to see if the results are different (as this would eliminate the possibility of the DB thinking i have the tiles when i do not).
