I also have a c5 ultra. After the last update Sony did (29.2.A.0.166), my phone couldn't read microSD cards higher than 32GB. And on the default messaging app, dates and time on messages I send don't appear anymore. And from what I read from fora, I wasn't alone. I wrote Sony an email and they advised me to have my phone repaired at a Sony Service Center, and was told I had to pay for services. So I didn't go through with it.

I've been getting prompts for this new update (2.1.12.0) everytime I plug my phone to my laptop. Based on my last update experience, I waited for topics about this new update here.

And sad to say, it's happened again. (SIGH) Sony what have you done? What a disappointment!

As i know there is 29.2.A.0.174 for some market, if you got 29.2.A.0.166, probably you will get 29.2.A.0.174 too. Maybe will be fixed problem in this update. I have C5 Ultra Dual, but again i stucked on 29.2.A.0.129 and i don't know why Sony developers did not released these updates for my region... And won't to say me that
