I'm thinking about replacing my failing Sony Ericsson with an iPhone but it is essential for me to be able to keep all information. The address book, the calendar and stuff like that seems to be easy. The sms-database on the other hand. I have not found any easy way to transfer them. In fact, i have not been able to find any way to transfer the information at all. I read somewhere that the iPhone store sms messages in an sqlite database. I guess that the database has to be backed up somewhere on my Mac when I sync the phone. My idea is to modify the backup so that it includes the messages from my old phone, and then and restore the database to the iphone. Is this possible? Preferably without jailbreaking the iPhone.
