I have an iPhone 5. I want to upgrade now but I've been holding off because I do not want to lose these texts. They go back to November 2013. I have a hard time even getting it to load past mid July. I do want it off my phone because it's obviously taking up a lot of space but I want the texts saved somewhere. Thanks for your help!
