1) When I go into Settings->SD & phone storage, it lists 3 things: SD card, internal phone storage, and phone memory. I understand what the SD card is of course, but what is the difference between "internal phone storage" and "phone memory"? I have 6.60GB total space for internal, and 6.25GB available. For phone memory, I have 748MB total space, and 600MB available space. 2) While on the topic of storage, I was wondering if anyone had any experience with the FiOS on Demand app, and knows how it stores videos. If you go to Menu->Help->FAQ, it states, "Downloaded videos are stored on the device within the FiOS on Demand app. Downloads are NOT stored on the SD card." I find this interesting because if I go to Menu->Download Queue, it shows how much space I have: 1020.2MB free, and 863.6MB used by "Misc." It seems like this is referring to my SD card (total space 1.84GB, available space 1.00GB). (I know I could test this by just downloading a movie, but there's nothing on there I want to pay for yet). 3) I'm interested in upgrading my SD card. It will be used primarily for mp3s, so I can ditch my iPod. What should I look for? Class 2, Class 4? My understanding so far is that the faster Classes really only matter for write speed, not read speed, so I'm assuming Class 2 will be good enough for my purposes? Any thoughts on the SanDisk Class 2 32GB? Amazon.com: SanDisk 32GB microSDHC Memory Card (Bulk Package): Electronics Thanks!
