eee, i don't like google+, it automatically transfers pictures from my gallery to google+ >.<

yeah, but i installed it previously, didn't know about it and it transfer my pictures over already...jahat punya google

Ha even S2 has its own issues. Rebooting/FC/occasional lags. Hei...this is android.
Its nor perfect OK? Welcome to android 

Cowithgun's ROM all based on malaysia version. Confirm got chinese. But I think the other version, forgot which country rom also got chinese. I forgot where's that though

I'm not using it. Can't give any comments.
Currently available rom (what I know) includes Kezra, Cow's (bionic/bionic2/etc etc) and CM9 (This one is ICS).
Cow's version done a lot of tuning for maximized speed and increased amount of RAM. Seems to be quite a good one but it's still Gingerbread. Some problem have problem using it though, not consistent feedback. I can't say much.
Kezra I got no idea at all.
CM9, someone here who used it says it's fast, even faster than cow's rom (smoother perhaps) but mind you, there're a list of hardware not functioning thus it's still a alpha release. The most important is... the camera is not working. That's what stopping me to go for it. This is not just a problem with Galaxy W ICS custom rom. Many other models are also having this problem. It's the lack of driver that makes those hardware can't be used. I know not much too. 

Don't forget that the Wave 3 feels like a premium phone with its superior build quality and materials. SGA was the phone that the SGW replaced anyways.

But overall, the SGA was a very capable phone and could run a modified Flash Player without difficulty.
In my opinion, it's one of the best Gingerbread based ROMs we can get for the SGW. It's tweaked and scripted for maximum performance and it really shows. AnTuTu benchmarks are off the roof with it and real world performance is extremely snappy when coupled with the included Zeam Launcher.

Arco's CM9 alpha too is another good choice since it's the only ICS ROM we have now. Though it's alpha, you can use it on a daily basis if the camera isn't something you use. Much smoother overall as well.

Heyy, up. do join us.
