If @p{(ul}you@p{??)} do, then it is possible to transfer the public/private keypair from your testnet wallet to your main wallet and recover the coins (but you'll need to use PyWallet or one of sipa's export/import private keys bitcoin branches). @p{par} Because the coins are recoverable, you shouldn't expect Mt. Gox to refund the transaction... (otherwise everybody could create testnet versions of their main-net bitcoin addresses, withdraw, and then as Mt Gox to "refund" their "mistake") @p{brk}
