Hi MetalJay,
Thanks for the reply. I do not have 4.0 yet and will wait to upgrade to it if this can be done. Both sms.db files are the 3.1.3 version. I wanted to find a way to do this without jailbreaking as well.
I have extracted the files from backups with iPhone Backup Extractor. so I have the two files free and clear and without jailbreaking. Through research the only way I have found to marge these is to really know SQLite well, merge the files through SQLite programing, jailbreak the phone, and insert the new SMS.db merged file.
Again, I do not want to have to jailbreak my phone and I do not know or have the time to learn SQLite righ now.
Thanks.
