Today my bitcoins were stolen by somebody. I had 2 unconfirmed transactions from last week. Trying to solve this problem I install Mycelium android wallet and exported private key from blockchain.info after that I have rebroadcast-ed these unconfirmed transaction with low fee. This did not helped me. Then yesterday I installed Bitcoin Wallet from here:

Last transaction was made for exact amount that I had from two unconfirmed transactions. I think last bitcoin wallet stole my private key.
