Retrieving deleted sms from sms.db
While searching on other sites, information was discussed about the deleted texts being stored in the /var/root/library/sms/sms.db despite being deleted previously. Also what I read was the only way to get to this database was to "jailbreak" your iphone, and is accessible only through a third party app, which I have no intention of doing.
My question is #1, is this information accurate that the sms are stored in the database despite being deleted?
#2 are there third party apps that allow users to access the iphone file system to get to this sms database that do not include this jailbreaking thing?
I do not want to do anything to the phone that would negate my warranty or go against what apple wants us to do, but if there are stored deleted sms on some database on the phone, and a way to get to them, i'd greatly appreciate any information on how to gain access. Thanks
