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.

  1. Gmail will ask you to login again if it detects change of SIM card.
  2. Gmail doesn't store your credentials in internal memory unencrypted.
  3. Phone has to be rooted to read from internal memory.
  4. Your phone can't be unlocked without the correct graphical PIN combination.

Will starting the phone in safe mode retain the lock screen or does it bypass the lockscreen? – Sparx Apr 30 '12 at 7:30
It will retain the lock screen. – roxan Apr 30 '12 at 7:47
How about gmail application and already downloaded threads? Has the lock screen some limit of unlocking attempts? Thanks – WebStern Apr 30 '12 at 14:53
@Steffen: I believe this is configurable, but from what I've observed, it's 5 attempts 'til a cooldown period of 30 seconds. During this cooldown period, you'll have an opportunity to use your Google Account password as an alternative way to unlock your screen. – ctt Apr 30 '12 at 23:55
@Steffen: As for your Gmail, although all communication with the Gmail Server is encrypted, synced messages are stored in the clear on your phone. However, as long as you haven't rooted it (and as long as your bootloader is locked, and your operating system is up to date), this database should be safe from other applications. If you want to ensure that someone couldn't somehow read what's on the internal storage without going through the operating system, consider full-phone encryption. – ctt May 1 '12 at 0:10
