What happened to itkorea4u.com?

I want to upgrade my phone, and the prepaid contract with them is great - 4,500 w per month, a little expensive for calls, but txts are the same price as any other network.

Unfortunately, they've disappeared.

Is it possible to get a different phone and continue the present d\contract which is with Skynet (Tfree), or maybe start a new contract with them?

I'd be grateful for any help about this. My old phone's keys are getting unresponsive, making texting a major pain...
