Hot spot wifi works fine but Crashes when selecting preferences ;(
Install Wifi Hotspot from addons (second download)
In short you really can't ask what's the best ROM and get a useful answer without telling people what you need and expect..
That's right. It's kinda very invidual thing and just after a long searching and trying you can choose which ROM fits you...
I'm using HyperNonSense by SpIder. If you want pure and light AOSP ICS - go for it :)
I wouldn't suggest you to stick it with a super glue. It can damage your phone and get worse than now. Try to find someone, who works with that things. good luck! ;)
