I have tried this ROM Beta1.
-Calibration is oke, Very good, but not perfect.
-Wifi works, but i did get a few reboots when turning off and on. (for me the reason to not use this ROM any further)
-LINK2SD works if installed.
-Settings menu sometimes very slow.
After first install and wiping before and after install. The rom was very bad working. But after first reboot again wiping. It was working oke. See above points.
This was the first Froyo Beta i did test. This because the calibration is good. I read the threads of all other ROMS for vodafone 845, but this seams to be the ROM with the best calibration.
Keep the updates coming, this ROM is very promising.
