Hi all I connected to Kies where it lells me that PDA:KG1, PHONE:KF3, CSC:KG1 firmware is available. OK - but what does that actually mean? I have searched in vain for some clue on a list of what has changed in this update. On reading a few other posts it seems some features in fact disappear if this firmware is a version of 2.3.4 - such as one I have used which is USB hosting. ie. connect a thumbdrive / MicroSD card reader to the bottom of SGS2 and it mounts under 'usbStorage'. Doing this is a little bit more portable than ripping of the back plate and then pull out the battery to get the external SD card out! So is there anywhere that details what is in KG1. Can it be reversed if I lose something that would rather keep?
