I upgraded OTA to the Firmware 1.2 - but Nokia removed a feature in the EMail client I would continue to use.

Is it possible to downgrade only the N900 eMail Software to the version from 1.1.1?

I wan't to sort sometimes all my Mails in the inbox by subject instead of receiving date. I used this until the update to clean up my Mails. But now its not longer working...

Here is my Bug report: 10660
Andre replyed today. It seems it's not a Bug. It was planned to remove this feature without announcement. And they don't plan to reintroduce this. Sadly, he posted no explanation why Nokia decided to remove it.
