Yes, yes, but it's still quite odd; you don't often hear about manufacturers/carriers underestimating their own devices.
In other words, has anyone actually tried filling a 64GB card to max capacity with data on the phone itself? Or is it only addressing the first 32GB like I would expect? Just because the card happens to be readable doesn't mean it's actually fully working like it should, so I'd still be wary about landing the money on a 64GB card for a phone that Sprint claims supports up to only 32GB.
If it *is* only addressing the first 32GB, then the only remotely possible option to get the full 64GB capacity is to re-partition the external SD as two 32GB (roughly; probably a little less) partitions. However, that's a *very* big "if" as to whether or not that actually works, since SD cards (and other flash-based external memory devices like USB thumbdrives) are designed (and expected) to have only one large partition. Similarly, you'd have to do some serious modding to get both partitions mounted (if the phone's card reader itself isn't the limitation).
In all likelihood, even that above solution would probably not work due to hardware/firmware limitations. This is similar to giving older computers big hard drives; even though the hard drive will certainly be usable, many older BIOSes are incapable of accessing anything beyond a certain capacity (in the case of an old Compaq laptop I have, that limit would be 10GB).
tl;dr: don't assume that the ability to mount the SD card automatically means all the space on it is accessible from the phone.
