I'm considering getting a Nexus 4, however I'd like to know if there's a way to do a backup of my GNex (JB) and restore to the new device (a bit like the iPhone). That's the only iPhone feature I envy. Note, I am not rooted. Is there a decent app out there that will mean I will get almost everything across in the correct state with minimal effort? i.e. SMSs, call log etc, but most importantly, app data. I don't want to have to do get all 3 stars in all Bad Piggies levels again I'm quite happy to copy my videos and photos on again, obviously contacts and calendar will sync straight from Google, but I really want to keep my app data. I'm presuming the standard google backup doesn't backup app data.
