    I wonder if there is a noticeable difference in performance between Class 4 and Class 6? I would assume that getting a Class 6 would be the best option.

    Not according to that list. There are a few class 6 cards they list as non-operable. I can speak from personal experience that the 32GB SanDisk Class 2 is not recommended. Next up for me is probably a Kingston 16gb class 4.

    The question I have is, "How much data do people have on the cards that are a. working b. not-working" I wonder if there is a correlation between a card that's got a sufficient amount of storage used. On my 32GB, I had about 20GB of music. Plenty of extra space, but also plenty used.

    I have a Centon 8GB Class 6 card in my Focus. I have about 7gigs left, so it is using the card. It has performed flawlessly. I installed it at the AT&T store on Monday, before I setup the phone.

    I've got the SanDisk 16GB Class 4. I've got about 12 GB left of free space so it's definitely using the card. I have had no issue on it so far and have been using it for about 2 days now pretty heavily.

    From what I have been reading, there are several other performance figures that matter more than the class rating. Apparently, there is a large gap in performance between cards with the same rating.

    Now I'm hearing it's difficult, if not impossible to reformat the card? Someone said Windows 6.5 can reformat it?

    Geez, this is one big mess.

    Update: Switched to the 16gb Sandisk from Best Buy today and the phone is responsive, holds data on soft reboot and all seems good. Its currently on sale for around $50.

    That is the same exact card I have (the 16GB class 4 SanDisk from BB). I have had it in for almost a week now and I have had no issue. You shouldn't notice any.

    Just an FYI, I switched to a PNY 16GB Class 2 card yesterday. So far, so good. No performance issues, rebooting, or data loss issues at all.

    I also formatted my previous Centon 8GB Class 6 card using a friends Nokia 5230. This is an S60 5th Edition based phone. So, there is hope on both fronts.

    So after reading the article on the home page.....microSD cards that are now compatible will be branded "Windows Phone 7 compatible?"

    Hopefully they got these cards right.
