• Print out the bingo card.
• Follow our the iPhone OS 3.0 keynote liveblog and take note of the timestamp as the event in the bingo card happens.
• You can shout bingo if you fill out one line or, alternatively, one of the four 2 x 2 brick groups.
• When you get a bingo, quickly send us an email including the events and their timestamps from our liveblog to email@example.com. Include "iPhone OS 3.0 Liveblog Pizza Bingo" in the subject, so we can spot your entry easily.
The first time we did this, lots of people forgot to put the timestamps from our liveblog. You must put these to participate.
The first person who sends us a bingo wins the prize: One free pizza (if there's pizza internet ordering where you are located, that is). Nothing like an edible prize to warm up my heart and my stomach. [iPhone OS 3.0 keynote liveblog]
