Partial update on this: we've discovered that the iPhone OS will shut down an iPhone's Wi-Fi connection after 30 seconds pass without any taps on the phone's screen. Apple made this change with the intent of preserving battery life on the phone. Since iPod Touches only have WiFi, they don't have this behavior.
One consequence of this change in the OS is that an OmniFocus sync that starts on wifi may end up finishing on the slower cellphone network.
In this specific case battery life is particularly important to the customer; if the 3G radio on the phone is disabled, WiFi will drop in favor of the (much slower) EDGE network.
I don't think this accounts fully for what Nicolas was seeing, but it's a contributing factor.
I'm unsure how/if the dev team will change OmniFocus in response to this discovery, but we weren't aware of this and wouldn't have figured it out without his help. At the very least, I figured a public thank you for his assistance was in order. :-)
