Accessing the internal phone memory by swapping out the SIM card Is it possible to access an Android phone's internal memory by switching out the SIM card? 

My Android phone, with no SD card, has been stolen but access to the phone is locked via the "graphical pin". 

Will it be possible to read internal memory after changing the SIM card? I am concerned mainly with the Gmail password I have stored on there.
Gmail will ask you to login again if it detects change of SIM card.
Gmail doesn't store your credentials in internal memory unencrypted.
Phone has to be rooted to read from internal memory.
Your phone can't be unlocked without the correct graphical PIN combination.
