I have some 80MB left on the phones memory, I have downloaded a lot of apps, tried them and deleted most of them (but far from all). There are still a lot of apps I would like to DL and try out, but before doing that I would like to move as much as possible to the SD card, it says I have 3.67 GB available, so plenty of room. However When I go to Applications--> Manage Applications the ption to move them to the SD card is grayed out and the option is not available to me. What do I need to do to turn it on? The HTC support page is not helpful at all in this case.
