Hello, I've been having problems with low storage space on my HTC Aria since it only came with a 2 gig SD card. I have been looking into getting a 16 gig one. But unfortunately I have no idea if it is a micro SD card or if I can use one of my extra camera 32 gig SD cards. Also, my screen is a little cracked along the top from side to side and the back is screwed in. So I have no idea of telling which one I can/can't use. I called my local AT&T store and they said they didn't carry it (since I bought it at Costco) and they couldn't tell me anything. Anyways, sorry for rambling. But my main questions are, 1.) Can a big camera SD card be used or does it have to be a micro SD card for the HTC Aria? 2.) Can I unscrew the back of my phone without anything happening to it? 3.) Does it have to be a certain SD card?
