Hello,

This happens only when my G1 phone is on T-Mobile network:

I found that when I try to go to the browser, and type the address

    http://i0.sinaimg.cn/

The browser tries to load the page, but no progress is shown for more
than 2 minutes.

(I have full 3G signal; all other addresses work just fine)

Eventually when I tried to access this URL in my Java code, I found a
similar long delay when I try to open the HttpUrlConnection, and
eventually I get this exception:

I/InetAddress( 1940): Unknown host i0.sinaimg.cn, throwing
UnknownHostException
W/System.err( 1940): java.net.UnknownHostException: Host is
unresolved: i0.sinaimg.cn:80
W/System.err( 1940):    at java.net.Socket.connect(Socket.java:1002)

Why would DNS take so long? Also, if my program tries to issue the
same HTTP request again, the same 2+ minute blocking happened.

Is this an Android bug or a T-Mobile infrastructure bug? It seems the
Android API should try to time-out faster, especially on the second
attempt.
