Nope, not got any further information on this. I have downloaded all of the following directly from the Huawei website...
... and have scanned through the upgrade guide, re: normal & forced upgrades.
It would appear from what you and others have said that B882 & possibly B885 have the option to turn off "increasing ringtone", but what I am still unsure of is if it is possible/safe to downgrade from B892 to one of the others, change the setting then update OTA back up to B892. Or if I try to upgrade to a previous ROM version will it fail or worse still brick the phone?
If anyone can offer advice on this it'd be greatly appreciated. Just to reiterate, I am on completely stock B892.
Edit: The other thought that I had is whether this would be fixed with the impending ICS update. It'd be good if the other two issues that I have with it were fixed with ICS too... (1) Music playing in alphabetical order rather than track number order (2) Unable to set the correct system voicemail number.
