My 52.39 btc is also 'missing' sent from one instawallet to another address and the coins are not showing up in the block chain, and the new address isn't showing up either cause its never been used.....
and yet on the address where the 52.39 btc were sent from shows unspent coins but they are no longer in the instawallet

The coins showed up to the sent wallet, so everything has been resolved. I know for next time to just use a bitcoin mixer and just pay the 1-3% fee...
You really want to lose your coins, don't you?
If you definitely want to do that, use the easywallet.org. The only online service that I have been able to keep BTC100 for an extended time without anything happening.
