32 GB Micro SD Card

---

I was wondering since I got the bestbuy protection plan if I could go to the ATT store and get the 32gb card since they say its compatible. Will they even put the card in?

I would say you can try. But the microSD card isn't supposed to be upgradeable; at least not by us, the users.

Your protection plan won't cover that. Once AT&T starts tinkering with it (or anyone else for that matter), it technically voids your Best Buy warranty.

Backup first!!!!!!

Happily voided my warranty 3 days ago :)

I can confirm the 32GB Micro SD from AT&T works in the Surround! Just a word of caution and should be common sense anyway. Backup everything, photos, music, etc before you change the card out. Make a list of your apps too. I know better but in my haste I forgot. I'm only missing a few pics so no biggie. Once I realized I forgot I figured I'd just swap the cards back later and backup pics again then swap the SD out again. DIDN'T WORK.

On reboot with the new 32GB card the phone will not see the new size of memory until you hard reset to format the memory. Once you enter your MS Live info again it will quickly recover your contacts then sync with Zune and restore all your media. Some apps will restore themselves (several I had deleted somehow auto-restored) but for the most part you need to search for them all over again and re-install. I miss the "auto-install" folder for WM6.5.

What didn't work was trying to go back to the original 16GB card. It seems the phone cannot reboot with a smaller card. That's the only conclusion I have. I hadn't tried to reformat the old card yet or anything. Putting the old card back just causes the phon eto keep cycling on and off to the HTC screen. Nothing else. Put back the 32GB card and everything is fine.

you could use any 32 gb card .. BUT 1 exeption card must be brand . sundinsk label does not mean anything .. you must confirm that card does not chineese fake .


succesfully used 32 gb card

SUNDISK 32 GB 2 class

before insert i confirm SN on sundisk site ..

A class 2??? I was thinking atleast a class 4 and preferably 10 if they make msd cards that fast. So how long does it take for you to sync with your class 2?

According to MS the class of the card is not the only factor.

"Determining whether an SD card is Windows Phone 7 compliant is not a simple matter of judging its speed class. Several other factors, such as the number of random read/write operations per second, play a role in determining how well an SD card performs with Windows Phone 7 devices."
