Question: new phone didn't bring in current info
iPhone 7 quit finding carrier signals (everything else was working fine) so I bought an 8. I backed up the old phone to iTunes before setting up new one. After all was said and done, new phone only had apps, pictures, texts, etc. up to the time when I bought the 7 and nothing from the 14 months or so while I actually used the 7.
Any thoughts on how to get those missing months back? Thanks
