xperia J update recieved todya and has fixed alot of issues be sure to get it. You Know where you heard it first from ---- Xavier
Why? I cant see update ?
Hi , I m here just want to know,I ve updated my J and everything going well but only one thing,GPS cannot be fixed shortly why??
This is a very minor bug fix but apparently same issues still apply, I have tested the phone extensively in the past 24hours and camera seems to have been improved but by that it has massively slowed the process of taking photos, so watch out there 1st, it has not fixed GPS issues yet, I took it out for a test and still same problems, WiFi problem not yet fixed tetsed this extensively.
That being said, I am waiting for a detailed description of the software update, till that is recieved from my trusted sources then there is nothing to ride home about here
connect via pc to get update
I also dont get the updates in via pc also, how come u get the updates? 
I also connected my J to PC but I cant update it. It says that Im up to date but I still have 11.2.A.0.21.
It seems its has ben released for some other regions of the world and some just have to w8 (don't understand this policy). also keep trying OTA
try OTA, if that doesn't work try PC at around midnight, i always get them at midnight
Confirmed improvements, RAM has more than 90mb free with sync, wfi and certain heavy applications running
