report from Threat Level, the FBI has been unable to crack an Android phone's pattern lock. When trying to guess a password, the phone locks up after three tries, requiring the user's Google account username and password.
Now, the FBI is trying to obtain the pimp's username and password directly from Google with a search warrant. They are also seeking instructions for overriding the security as well as any information Google may have related to the phone (such as email, contacts, GPS locations, and Internet history).
CLARIFICATION: The fact that the FBI is requesting the username and password does not mean that they cannot obtain the data that is on the phone without it. The memory can be accessed through a forensics investigation, but there is a slight risk of losing information in that process. Getting full access to the phone will remove that risk.
