The popular QWERTY slider E75 has had a firmware update today, to v211.12 (from v210.12), not available over the air for me, but there via Ovi Suite and Nokia Software Update, as a 146MB download. The E75 has User Data Preservation, but backup anyway, just in case, beforehand. The update is mainly bug fixes, listed below.

Official changelog summary:

• Corrections done concerning e-mail client: contacts and calendar sync starts failing specifically with exchange 2003 SP2 server

• Corrections done concerning OMA DM remote configuration problem

• Corrections done concerning FOTA server profile, wherein PC-suite has been set as the default profile instead of Nokia, this has been corrected.

• Improvements to the device lock functionality

I'm guessing there are also point updates to core components, comments welcome if you spot something else new!
