network issue

[salian]

Wonderful phone with few bugs, i have faced complete shut down of network, though the network was showing available. I neither could make calls nor receive, my friend was trying to call me and he could not establish comtact. I am planning to use this phone for atlease one full year or may be more hope sony rectifies these problems

Same problem for me! Have to restart phone several times a day! Network seems ok for both sim cards in the notification bar but impossible to make a call, no internet connection, messages not coming in... 

We need a fix quickly as this makes phone completely useless as you may miss lots of important calls!

Come on Sony!
