I noticed following bugs: 1) The 'Network type selection' in the Settings | Mobile networks menu is not working. There are 3 possible options, but the type selection change will not take effect. The phone always automatically switches between 2G/3G even if I select 'Only 2G' or 'Only 3G'. 2) In the 'About phone' the 'Status' menu is not working. If I select it, the empty list is shown and the phone will freeze and in a short time it will reboot. This was the same also in the version 2.3.30. Phone model: SGS2 GT-I9100 Baseband version: I9100XXLPS Kernel version: Siyah-v3.3.2 Build number: MIUI-2.6.22 IML74K Before install MIUI, I have done the full wipe in the CWM.
