I use a PC as my platform - We have an iPad 4 which seemed to have no problems with updates - lust done the Ios 8.1.1. My granddaughter (19) has a iPhone 4s and as we heard of issues on that device with Ios 8, she has yet to update it - and has still got iTunes 11. I found a few issues with iTunes 11 which I have now sorted (got sidebar back using "Playlists" !). I have suggested to her that she shoul now update iTunes to v 12 on her PC then plug in the I Phone 4 and update with Ios 8.1.1 which I believe specifically addresses the former issues with the 4s. Anyone with a 4s with suggestions?
