Hope i help you....
That's what I did...
You could just delete an entire tree at a time though.
I had the same problem (like most of us who updated firmware AND made backup). After I saw that nobody has a nice solution, I tried searching the net and market for an application that could delete duplicate messages. Didn't find it, but...
I installed app called "SMS Quick Delete", it has the option to select multiple messages inside a thread, or whole threads and then delete them all together. Oh, and one more thing that annoyes me with normal inbox, but works well in this app - after you delete message, it stays right there where you were, it doesn't scroll to the end of the thread.
Hope this helps.
