Give it a clean and take it back to your friend.

too late ....unfortunalety

I think the warranty will only cover the original buyer, so they need to get it sorted.

The only other option would be to try Sony Update Service online.

get a brand new "MICRO" sim card, do you have a micro sim card or did you trimmed it? most of the time this is the issue.

I agree with miffy you should repair it with either PCC or SUS

Update Service (SUS)

meybe when new Android Update will be available than problem will be fixed???

anyway , anyone knows when new Android update for Xpeeria T will be availiable?

Hi

Im sure now the problem is when DATA TRAFFIC is ON

until switched off Internet and not using internet,  phone works ok.

when WIFI or DATA is ON  , phones keeps restarting after few minutes using of internet

any sugestions?

PCC , SUS tryied and still have problem. New micro sim also have.
