Something very strange happened today. blockchain.info let me send 1.48 BTC when I only had 0.6. I had a incoming transaction of 1 BTC. For some reason it made the sending transaction twice (received and sent BTC in the same block) and it is displayed as unconfirmed and my balance is negative.
-snip-

The only simple question that i can ask you is that why would you even try to spend 1.48 btc when you know quite well that you have only 0.60 btc?

0.6 + 1 > 1.48

"Something very strange happened today. blockchain.info let me send 1.48 BTC when I only had 0.6. I had a incoming transaction of 1 BTC.."

He had 1.6 BTC and try to sent 1.48 BTC but the payment show two tx id. (or double spent)
I don't know about this matter. You may contact blockchain.info support.

My point exactly, thanks for writing it out.

Can I remove the unconfirmed transaction?

All scammers also want to know "How to cancel the unconfirmed transaction".
The answer is, you cannot. But to make sure some big payment in transaction. It's better to wait until 3 confirm.

Of course it can be removed from the wallet, the rest of the network probably forgot about it already. The unconfirmed TX is invalid as the identical twin with the different TX ID was confirmed.
