Mysterious Android connectivity - part 2

(Continued from part 1.)

Running OS Monitor and clicking the Connection tab gives you a little more information than the command line; anything with a SYN_SENT status is not working correctly.

Google Bookmarks Sync

wg-in-f188.1e100.net:5228 SYN_SENT

Google Services Framework
wg-in-f188.1e100.net:5228 SYN_SENT

Samsung Push Service

eu.west-1.compute.amazonaws.com:5223  SYN_SENT

AllShare Service

(Appears to be attempting to connect to something on my subnet) SYN_SENT

So let's try disabling some things

Settings > Accounts and sync

I have everything but Google disabled, and within Google I have the following ticked:
Sync Blogger
Sync Calendar
Sync Chrome
Sync Contacts
Sync Gmail
Sync Internet

So untick all those, disable Accounts and sync for double-measure and restart the phone (not sure if it needs a restart, but hey.)

And the result? It's still syncing stuff!
  
Samsung Push Service

eu.west-1.compute.amazonaws.com:5223  SYN_SENT

Google Contacts Sync

wg-in-f188.1e100.net:5228 SYN_SENT

So Google contacts may be syncing on startup regardless.

After ten minutes or so all the SYN_SENTs timeout, but Google Services Framework soon starts up again and fails to fully establish a connection. Perhaps we could make it use port 443 instead? (Like Maps and several other things do quite successfully.)
