Using a phone without data plan for multiplayer game dev I would like to try out android programming and specifically try my hand at some multiplayer development, but I no longer have an active phone plan for my android phone.  Is it possible to just use wi-fi without having a 3g data plan?  There is no need to make calls, only access my wireless network.

[Edit] The phone is a Galaxy S Mesmerize if that helps.  I'm at work, so I can't take a look at the phone to see if it needs a SIM card.  It was from US Cellular so I don't think it needs one.  Not sure tho.
Depending on the model/carrier - your unit could block the access to the UI (past the "Emergency calls only" screen) without being activated. If you can root the unit - this can be easily bypassed.
