I use the decipher text message tool. Works great for saving text messages to your computer from your iPhone. I usually back my messages up about once a month just for safe keeping.
actually i found a way to save ur messages without spending any money, or any software. So on ur iphone, you know how when u look at a text message and on the top right there is button that says "Edit"? Well when u click it u have an option of either deleting specific messages or fowarding them. In this case, all u need to do is tap each circle which checks of each of the messages that u would like to foward. Then once you have clicked all the messages that u would like to save, click the 'foward' button on the bottom right. This will bring u to a new message screen where all the messages will combine into one text message. All you need to do is type in ur e-mail address as the recipient and then ur text messages that u would like saved will be sent to ur inbox. that simple. Much better than spending money, or downloading software that u have no idea how to work.
**for long messages that you want to save u might have to go back and forth and save seperate parts instead of doing the whole thing at one time.
True this works but for a long ongoing convo it's too long and from my experience having tried this awhile back, when you open the email you sent yourself, it does look like one long run on sentance where you can't tell who the sender and recipient is.
If you want a easy and cheap "what you see is what you get" program I'd buy the Deciphertools.com thing for $9.99. Just bought it a little while ago after wasting $20 yesterday on another crap thing that wasn't cool (too bare bones). This one works great, saves easy, exports anywhere, etc.
One thing, it doesn't highlight senders texts (my outgoing) in a lime green colour like how it looks on the iPhone, it's more a plain grey, but otherwise looks the same and includes attchments--> Important! Not all services do...
iPhone SMS backup file location in Windows
Since there are multiple versions of Windows, here are the possible locations of the iPhone backup file:
%APPDATA% = C:\Documents and Settings\[your username]\Application Data\
%APPDATA% = C:\Users\[your username]\AppData\Roaming
Everything else is the same as above, look for the same files and you’ll need to open them in a SQLite editor.
but also them cannot read as they are an inaccessable format, you need to extract them and read it, therea are many app can do that: like iStonsoft, iPubsoft, Vibosoft and more...
