My neighbor was hating her old messaging phone and after putting up with me rambling about my Droid, and she snuck out behind her husband's back and bought a phone off of CraigsList. It's a HTC Aria from some guy who claimed to be a repairman (unassumingly a phone repairman). It looks brand new and she made him put her sdcard in and show her that "everything" worked. So I'm looking at it, trying to keep myself under control from suggesting everything under the sun, when I notice SuperUser app. I downloaded Astro and was able to navigate to /system/app and I got only as far as long pressing an apk and get the pop-up. So, is the phone rooted? what else can I do quickly to check?
