After testing both stock 2.1 and 2.2 and different rom bakes, the conclusion is that the Incredible for some reason does not really have "true" apps2sd (as define by Android). It appears that regardless of if most of an app is moved to the sd or not, the total available app space is nowhere near even the 748mb on device and the ceiling is actually around 500mb when "low on space" errors begin popping up. Key example is when apps are shifted to the sd, the low on space error still happened, regardless of cache and message spaces being clean. I tested this with stock as well. The app install space is not to be confused with data downloads that some apps automatically install to sd (games like Quake, Nova, etc), but the actuall apps2sd move process in the app manager. It does not matter where the weight of the apps is installed, since whether having 300mb apps on the device and 200mb apps on the card results in the same thing as 500mb of apps on the device and 0mb apps on the sd- low on space is the result. On the Incredible, apps2sd is really app displacement. As a result, it is better not to use apps2sd, since saves space on the microsd card and makes no difference to the amount of apps you can install. Also, there is no way to get anywhere near the 748mb, yet alone having that much on the device and part of apps on the microsd (total would be a more than 748mb). added: A few others have noticed this now too, but makes sense only some of us see it, since not all folks are app hounds.
