OK. Let's do some simple network diagnostics.
Could you try to install "tcptraceroute"?
Try:
tcptraceroute <servername> 443
to two server names: one that works, one that doesm't.
Here are the results from my 3G connection to google.com port 443 (the
https port):

Could you also try "telnet <servername> 443", again for one that works,
one that doesn't.
Here's one that doesn't:
pbarker at bluebottle:~$ telnet smh.com.au 443
Trying 203.26.51.71...
^C
pbarker at bluebottle:~$
And here's one that does:
pbarker at bluebottle:~$ telnet google.com 443
Trying 74.125.237.50...
Connected to google.com.
Escape character is '^]'.
^]
telnet> Connection closed.

And, by extension, more battery life - which is the sucky bit :-)
