Yesteday I was trying to update my Xperia U to ICS but PC Companion was with a problem, in my desktop computer it says that it can't isntall sony drivers or something like that and says to try again later when I'm trying to update. I've tried to do it with my notebook and the same problem happens. But today in the computer where I work it can't even update the PC Companion components to the newest version, says to try again later. Is this a problem with sony servers or something else?
No one has an answer? Can someone at least confirm it's a problem from sony side?
Hey deathm00n,
I have the exact same problem and I know for a fact it's a problem on Sony's end, of course, when I raised the same issue, "super-users" come around talking about SUS and how it can't possibly be a problem on sony's end. I'd say give SUS a try (it didn't work for me) but the least I could do was let you know you're not alone.
If you look around you'll see plenty of threads with a similar issue.
What is SUS?
Use SUS (Sony update service) to update your phone 
How can I access it? Is it from my phone or a application for my pc or a site?
it's for pc , download it from official sony mobile website
