What's up with Sprint (NYSE:S) today?

Apart from the usual T-Mobile takeover chatter (prolly bogus), I'm hearing:

- Clearwire CEO tipped the market that it is talking with EU counterparts on Wi-Max venture.

- Samsung's Instinct phone has been huge in the first month of sales. It's reported some Sprint stores are out of stock already.

That's what's driving the shares today.

fyi
