I use ITP www.itp4you.com $20 a month unlimited. I have a cordless phone plugged into it. The adapter is in place where a router would be. Be sure whichever way you go you bring it in your checked bags. You don't want to wait a month for your phone to get here.

Some things to bring. Stock up on your favorite brand of "whatever" and TMO it. Whether it be your favorite bar of soap, shampoo, deodorant, Mint chapstick Chances are you won't find it here. You'll just end up stocking up at Osan for a higher price.

A few things I forgot to bring and HAD to have shipped: Airman's Manual, extra reflective belts, Cold weather gear.

Things I wish I had TMO'd but not worth shipping: hiking boots, golf shoes.

Oh yeah, MOST IMPORTANT: get and setup a SlingBox. It is the best thing ever. You can read my review here

does ipt4ypu still work after they disabled the vonage for everyone?

Mine still works. I have heard that Lingo? works as well.

If you PM me your email, i can send you a link for your first month free.
