iMessages Compression for message history Is there some way to compress messages for iMessage? My friend and I talk a lot and at the moment between all of the attachments and messages my iMessages is taking 2.5G of space on my phone.

What can I do to compress this data or back it up or something?

Thanks.
I think that the best way is to extract your messages and back it up manually.

For example :

After that, you can zip it :)
