Yes...I have taken my card out and placed it in multiple and ensured that it clicks (I have to use my stylus to get it in there fully). I've also tried the factory card and the one that worked flawlessly in my Mogul and I've had the same issues and it seems to happen once a day.

No issues here had the touch and been playing with lots of apps daily since 11/4

No issues here. I got my Touch about a week ago and through in a SanDisk 4G SDHC card. Ton of Music, Movies, Apps saved on card.
If I were you I'd take it to a tech or exchange the phone while you're in your 30day warranty window.. Dear God if I have to send E-care 10 emails again.

my mfr date is 10/4/2007

I mean i never physically touched it again, coz its so hard to reach anyways, and i always use teh cable now. i have around 1 gig of files stored in my card and they are accessed daily, and all my programs are on card like wa3, wad, s2ul2...and a lot of junk that i install/uninstall/reinstall on a very regular basis thru the usb cable. not a single file has gone missing yet. My mnfr date is 10/27.

My mfr date is 10/4/07 btw.

Update: Took my phone to the Sprint store and they replaced it. We'll see how this one goes.

i had a 2gb card in my Mogul (before Sprint exchanged it for the Touch). One day my memory card was unreadable so it asked if i would like to format. I told it "yes". It formatted and then displayed folders with foreign characters. I was unable to open any of my files. After ejecting and re-inserting the card, my phone was unable to even recognize it. My Touch cannot recognize it either. I've even tried to do a format on the card with a Card-Reader on my PC and it won't recognize it.

Any idea's?

No problems here. Mfg 10/13.

Sandisk 2GB.

No issues here with a 2GB Lexar card that I use for cabs and mp3s.
