• Getting onto the Hopkins wireless network from the Droid requires a few set-up steps. Here are newer instructions from JHU IT. I don't think you need to type WIN\ before your user name. The trick is getting a wireless connection long enough to go through the JHARS registration using the browser on your phone. Also, there is a wireless timeout setting you can access by hitting the menu key when in wi-fi settings and choosing advanced. It might help to make the wireless sleep setting "never".
• If you want to view your phone on your laptop, download this application: DroidScreen. Follow the set-up instructions regarding the Android adb. You will also need to set the phone setting: Settings -> Applications -> Development -> USB debugging ON. Windows users may also have to grab a USB driver from motorola: http://developer.motorola.com/docstools/USB_Drivers/.
