My Streak has missing parts?

[Guest a_friend]

I only noticed this when I dropped the streak a few weeks ago and needed to open it up to push the internal SD card back in as it would not boot up.

The 2 torx screws at the microphone end are missing, the Device was bought (£429) from Carphone locked to O2 back in June last year now unlocked by O2.

What kind of QA process did Dell go through to get these early devices out I wonder? how many more are missing these screws adn where can i get some replacements from size etc?
