TrackMyPhone v1.1 has been submitted to Apple.  Instead of waiting for a big release, I decided to submit what I have done so far and continuously add features.  This update has:

• New App icon (by Keherance) and display name.
• Updated UI.
• Can view locations in app on map (last 10 or current).
• New settings screen.
• Passkey to unlock the app.
• For iPhone 4, front camera will take picture on unsuccessful unlock attempt and email it to the address associated with the account.

Should hopefully be in the App Store in a few days.
