Don't update to this firmware!!!! I'm in UK and upgraded on Friday. Phone function and contacts stopped working after the upgrade. It keeps crashing every time I go to contacts or call log. When it crashes it gives this message :'' Unfortunately, the process Com.Android.phone has crashed.''
Nothing helps, not even a restart. This is really rubbish that from all function that Sony could have messed up following a firmware update is the actual phone app. I have no clue how to fix it.

I dont have the problem on latest update
Yah, always just put the blame on Sony hoping the problem goes away. Well, here's your solution which is not even new:

'bearings'. Thanks for your answer. Can anyone also provide a solution that works for more than 5 seconds? 
'alexdon', I will try this today as trying removing the cache and data from the phone and contacts app as suggested above, fixes it temporarily. I find that a few minutes later (or rather browsing the contacts on the phone which makes the cache grow again), clicking on the phone app or going to contacts makes it crash again.
When it crashes, other than the 2 consecutive popup messages telling about the services that stopped working, the signal gets lost (red X) AND SIM card has a red X on it. This goes on for a few seconds until it restores connection again. Any idea?
As mentioned, had no problems before the upgrade last week.
i tried software update but it still crashes when i go to phone or to contacts.
