Google has just released a nice update for Google Maps Mobile, including StreetView and walking directions! This update is for Blackberry and other Java-enabled phone for now (no Symbian or iPhone yet), but other devices are coming soon.

The Symbian Blog has a great review of Guardian, software written to help protect your phone from unauthorized usage. For most of us, that means trying to get it back if it’s been stolen. Once configured, you can send an SMS to the phone and it will silently send back a wide variety of information.

Among other things, it can:

• Password protect various applications in the phone.
• Auto-send an SMS to another phone if the SIM card is replaced. The message includes the new phone number of the device.
• GPS. It can access the GPS device in the unit, and send an SMS with the latitude, longitude an a Google Map of the current location of the phone.
• Alarm. You can send a message to the phone that will force a very loud alarm to go off, regardless of what profile is active.
• Logs. It can send you the call/sms/contact logs.
• Fake SMS. You can send an SMS to the device, but pretend that it’s from someone else. The example shown is an SMS from “the Police”.

The only catch is that the thief can’t flash the phone, which any smart thief would do. However, if they fail to flash it, then you’ve got some great tools on your hands to try to track it back down!
