SMS & Media Manager for A800

I realise that this maybe be slightly off topic but I'm seeking some guidance from the experts here.

I have a Samsung SGH-A800 and am looking for a way to delete SMS from the phone via the PC. [It takes so long to delete each message at a time and i don't want to simply delete all!] Ideally I would also be able to...
a) Copy SMS from phone to PC and back
b) Move/Copy SMS from SIM card to Memory and Vice-Versa

The main advantage of such an app would be that it could do Multiple-Select...i.e. you don't have to move/delete one SMS at a time but rather highlight a few and apply move/delete to many SMS at once.

Doing these functions on the phone is rather slow, and Samsung have been really ignorant in this respect because when you delete an SMS you get taken back to the first message in your inbox or outbox respectively and have to scroll all the way back to delete the following one - This is an issue with all the new Samsungs. Also I noticed you can only move SMS from SIM to phone memory but not vice-versa!

I'm also looking for a way to upload/edit ring-tones and images for the A800 if this is possible.

Any advice, tips, or links to software which could help me accomplish any of these functions would be greatly appreciated!

Thanks,

Sahkan

POLL: As a sumsung owner, would you find a piece of software which fulfills all these tasks to be useful and be eternally grateful to the programmer who made it?

A) Yes, I would build a shrine in his/her name!
B) No, I'd rather be downloading pRon.
