I'm just wondering about syncing - first, it says in the quickstart manual how to mount the storage card onto the PC, but how do you "unmount" it? secondly, do i need any software in order to accomplish syncing onto my pc -- reason i ask is because of this download i found on the htc.com website --> HTC Mobile Phone Support - DROID ERIS by HTC (Verizon) - Downloads what exactly does that do? i know it says sync update but is it referring to updating an application on your pc? i don't understand what this update is. Thanks for any information!
