Hi all,

had my xperia arc since aug/sept last year. originally had problems with random rebooting which seemed to stop after a software upgrade.

But now it seems to have started all over again. it's favourite time for rebooting is about two minutes into app usage (and it dosen't seem to matter which app)

its running 2.3.4

i've restored it back to the factory settings but as soon as i install any app from the market it starts again

i;ve done the removing of batteries and sim cards and the problem persists

it also does it on some phone calls which is rather embarrassing !

any information would be grateful as the phone is fantastic while it works !

regards

go to settings -> about phone -> check the Build Number

sorry for the delay

the build number is 4.0.2.a.0.42

i've narrowed down the rebooting to after market apps at about 2mins into the app

and the odd long phone call !

also every time i change netwoek mode it loses all signal although vodafone asssure me the signal is good, although they don't seem to know anything about wdcma !

the only option it actually works on is wdcma(preferred)/gsm

any help would be nice !
