Updating problem with gprs network connection.

What steps will reproduce the problem?
1.Run the app under grps connection and get proper weather info.
2.Start a working wifi connection and then disconnect it. Then wait for gprs 
work again.
3.Then try refreshing weather info.

What is the expected output? What do you see instead?
expected: Get weather info refreshed.
instead: The app stuck and never get new weather again, even I force it refresh.
