True, since the bootloader is not locked, it is very hacker friendly unlike other manufacturers.

Quick review of simply galaxy sweet rom  (what a mouthful!)
- beautiful honeycomb theme - modified circle battery mod, icon, dialer, among others.
- everything is faster than insanity. Maybe because animations are all off compared to the previous rom and I have avoided installing apps that may slow down the phone.
- idle battery drain is excellent. 5%/9 hours. Will test this again tonight.
- there are few unnecessary apps like quick boot, social hub,memo and others. I think they try to make a complete rom. Certainly not a minimalistic rom like insanity. Of course, can change all this manually.
- finally, spb shell works, insanity 0.5.3 didn't.

So far I'm satisfied and will stay with it for a while. The rom maker seems like a cheerful and friendly person. Recommended.

If from darkyy, the rom maker said better to flash stock firmware first (start fresh and clean, preferably eclair rom jm8 because it has 2e recovery) because darkyy rom is difficult to remove. With 2e recovery, download both 2.2 base and 2.3 update with a reboot in between.

For other rom, just download both cwm zip file and flash from recovery mode, with a boot in between to let it deodexed.
