how's the battery performance after JB? any better? still waiting for the official update 

just check OTA and via cable, still no update for my ION.
maybe they are rolling out start from 1st batch to 2nd batch?
I bought mine Jul/Aug 2012 if not wrong.

Official JB update should be almost no bugs or less buggy than the leaked JB...

As the leaked JB rom for Ion is actually for test purposes and the kernel provided by dev in XDA also for
factory phone but re-coded...So better wait for official JB, almost half a country in the world is receiving the updates
from OTA, so our country should be around the corner...

Btw, youre using the De-Bloated JB ?

So its fresh stock firmware? Nice...Is it still buggy? Performance and battery life improved?

Buggy when playing HD video ?? Thats weird..I remember my Ion last time using JB Adreno driver i extract from the leaked JB and install it on my ICS....Even benchmark proved that JB driver is even better...

Maybe its the kernel problem

Bro guna JB .204 or .203 ?? or .211 official?

Hurmm...Try re-flash la bro...Data Wipe/Format buat twice...

Or else, re-flash latest CWM yang stable utk JB, new version..Then re-flash rom firmware

so far very (.211).. very smooth but occasionally keyboard lag... I downgrade the cpu to 512.. batt can tahan 2 days.. but still very smooth..but then I just use a phone/youtube/browsing..... no gaming..

Dont know why, bila lock screen guna apps lock screen tu, dia menyala sendiri lepas lock. Then, bila guna unlock key, tekan sekali hanya lampu button yg bawah tu je menyala, kene tekan sekali lagi barulah boleh nak unlock screen.

Hi. Noob here. Do I need to update to jellybean by myself? Why sonydont auto update my ion? I found software update section under about section.

I dont want to root or jailbreak or anything as I have no idea.

my volume up button always lost function == have to make a restart

for me JB ni not the best la..

1. incoming call voice always slow and i'll have to push volume + to increase it.
2. app screen off and lock not responsive very well with JB.

lastly i'm reverted back to GB rom..smooth and steady even it now outdated..

Not so many choice custom rom for ION rite?..
I've tried almost all custom rom there..
OC kernel even less available..
Look like development for our phone is really slow..
Little bit jealous looking xps & acro s development thread..

Guys, any news regarding Xperia Ion official JB update? Already available or not?

The only complaint I got with the official JB for ION is that..

video recording for 1080p LAGS mad =.=

battery were better than ICS, to my personal opinion after using for about 3-4 weeks now.

Update using PCC, SUS or OTA?

Anyone had try xzx_v2?..Is there any bug for that rom?..Feeling boring today..Look like I want to change ROM for raya..

Use offical rom is the best, stable!

I'm already using JB leak 203, 204 and stock 211 JB..I'm not satisfied with current volume bug..

just flashing xzx..I'm notice cannot use retro clock widget pulak..haish..that app make my phone not going to deep sleep lor..and 1 more thing this rom really hunger for RAM..
