The sync feature is handled by Amazon's servers, but calibre makes it possible to utilize the sync feature on ANY .mobi file, regardless of origin, (retailer OR conversion). It's all done completely in the background. However, for it to work, one MUST be using the Kindle for xxxxxx app (iOS, android, blackberry, etc), and/or kindle hardware -- though the hardware is not required. It's all done in the background, seamlessly.

The free readers will do that job for free. You don't have to use those readers to read anything - you can use them just to do the transfers if you wish.

This is, yes, another method of doing it. However, within the context of this thread -- ie, page syncing -- you couldn't use those free apps to read the book and get the sync feature. You could, of course, use them to get the book, and read it, so long as you didn't look to be at the same place in the same book on another piece of hardware. So for this OP, it seems to me that since he HAS to use Kindle for Android (and WANTS to), for the syncing, it'd be redundant to use one of those apps.

Like you, I'm not trying to steer anyone one way or another. To me, the sync feature is well worth limiting myself to Kindle for xxxxx. To others, it might not be. To me, the 3 bucks for ACL to easily transfer my books was worth it. To others, it probably isn't.

If the OP was using the Calibre Library app, I assumed the OP wasn't using the Kindle system and didn't get page syncing. Am I wrong? Did I miss something?

I believe he was not using the ACL app at first, but WAS using Kindle for android. However, since he was attempting to get the sync features on .mobi files that he had not either acquired from amazon, or converted in calibre, the feature was not enabled. Now he knows what to do, and he knows all his options for the various ways of doing it.
