Hey, I just got back to the US after being overseas when the whole smart phone thing was blowing up here so I'm fairly new to these devices (I left with a first generation RAZR if that's any indication to how far removed from cells I've been). Just picked up an Xperia Play and was wondering about some things.. Is there an easy way to go about altering my phone's startup and notification sounds? (preferably without rooting, but I'm not against it.) Also, where should new ringtones be placed and what file format should they be in? Thanks for any help.
