The W550i has some functions which the W800i doesnt have like

1. When sending a message, it sends in the background i.e we dont have to wait for the message to be sent like in the Nokia symbian phones.

2. It has Editing options while messaging like Copy and Paste.

So could you guys tell me if its possible to modify my w800 to have those functions or does the new firmwares for the w800 already has those functions.
Am currenty using the R1DB001 firmware.
