According to a recent report by One FPS, just 50 percent of all iPhone’s that have been brought into the Genius bars at Apple stores have been backed up and synced with iTunes.
This seems like a really high figure, and would mean that half of iPhone users don’t have their iPhone data backed up, opf course the users had to connect their iPhone to iTunes when they got it to activate it, but it is surprising that so many would not connect it again to back up their data.
A little birdie says that about 50 percent of Apple Store customers who need to get their iPhones swapped have never plugged them into iTunes after the initial activation and sync. This is a big reason, according to this birdie, for why Apple Store Geniuses are excited about iCloud.
Obviously when Apple introduces iCloud, these iPhone users will have their data backed up to iCloud automatically.
