Updated and giving the sqlite a good work out. Some things i've noted so far:

1) On the initial switch it didn't import the tiles i already had into the DB. Not sure if this was just doing something wrong on my part or if that just how it is.

2) When downloading for a particular zoom level, it downloads according to the zoom level used in the map scaling preference. For instance, if i have it on x2 scaling and i tell it to download, it downloads the levels below, which it should but it's not clear if that is all it is getting or if it is also getting the actual zoom level you are on (assuming "0 down/up" as the batch download setting). Of course when i first fired it up i was forgetting i had the scaling on and so when it told me it needed 330,000 tiles i was a bit taken aback. 5KM around from my location at the zoom level i was "at", visually anyway, is only about 25 tiles when using the scaling. I figured out that it was downloading the actual zoom level and not the current displayed level of zoom.

3) When there are large numbers of tiles being downloaded, say over 400 (as i've done a couple different batch downloads), the count downloaded doesn't update until it is finished, so you have no real idea how much time might be left in the download.

4) When there are large numbers of tiles to download, and you "click to estimate size", it simply freezes the phone for about 30 minutes and then causes a hard reboot. Download sizes that have caused a reboot when estimateing, 48K, 98K, 330K, 498K tiles. I've since stopped asking for an estimate and have just gone ahead with downloads (though i jumped from 400 to 98K in my downloading. The data counter is spinning so i know it's working, but as mentioned in 3 the display in modRana isn't updating). Even with a small amount of tiles (400), the estimation took a long time to finish and hung the phone for a few minutes.

EDIT:

5) Large tile downloads take a lot longer to download than you would think. I get about 100KB/sec down here at work but the download (which is using almost 96-100% cpu) is only piddling along at about 12.4KB/sec. is there any way to get it to us more bandwith and finish sooner?
