There are lots of things that can wake up the phone.
So are:
 - 3G chip signalling that something important happened
 - character arriving on a UART (from console, bluetooth, GPS)
 - power button, aux button, screen tap
 - USB plugged in/out

Your wakeup happened 626 milliseconds after it went to sleep.

Was the GPS chip on?  That would do it (it reports every second I think).
If so, you need to turn it off or tell it to stop reporting when you go
into suspend mode (or generally when you don't care what it is saying).

Of course it might be something else...

Hope this helps.
