I’ve been asked this question a few times and I’ve seen it asked in forums before

How do I find out my Android phone’s Mac address?

Its really simple, actually.  From your home screen, just go to Menu > Settings > About phone > Status

From this screen you’ll also be able to tell your:

• Battery Status
• Battery Level
• Registered Phone Number
• MEID / IMEI
• Network status (What shows up here depends on whether you have a CDMA / GSM phone)
• Signal Stength
• Mac Address
• Bluetooth Address
• Up time (How long your phone has been running since the last time you powered on
