SMS Restore?

[hermy65]

This is driving me absolutely crazy. I decided to sbf to 2.1 then update to the newest leak of 2.3.15. Once i got it up and running i sent maybe 5-6 sms messages. Yesterday morning i woke up and somehow my phone had restored like 8000 sms messages that i had sent prior to sbf'ing and whatnot. I initially assumed that i had left the checkmarks by google backup and auto restore but they were both unchecked. So i deleted all of the messages and went back to normal using it, this morning i woke up and all of my messages had been restored....wtf? Can someone please tell me how to prevent this from happening?
