I bought this card to replace a lost 16 gig in my phone, (HTC G2). Seems to be working perfectly, so I will recommend to all. WAIT!!! read on...I had this card in my phone for a little over a month when it messed up. The phone stop recognizing the card, tried it in the computer and it was not recognized either. I contacted San-disk and they did send me out a replacement but I lost the few pictures I had on the original card. I could have sent the card to San-disk's data recovery people and they would have charged me $275.00 if they were able to recover the data and nothing if they couldn't. A bit to rich for me so I passed and unfortunately lost the photos.
