Is there a block-diagram available online?
If the mobilephone power-supply is alredy regulated to 5V, why would the USB's need further regulation?
What are the voltage swings on eth0 lines?

there's a full schemaiic esily found using a search engine. I've not looked for a block diagram.
The USBs 5V output is connected fairly directly to the 5V in. see above for more detail.
ballpark 3V - look it ip on wikiedia.

And othe bits also run at 1.8v too so there are two linear regulators to cope with that.
