Not going to say much. Just that you can get the Samsung Galaxy Nexus (the international GSM version) unlocked for $459.50 via Negri Electronics, with free ground shipping. Here’s the link.
You do have to live with a NTT DoCoMo logo on the back cover.
Update: As AceCurry and the guys behind the offer, Negri Electronics, have both confirmed in the comments below, 3G data will work for those on T-Mobile. I had erroneously stated that it won’t. Sorry about that, everyone.
