Recently, back up times have been stretching to near 30 - 40 mins for iPhone. Previously it used to be no more than 5 - 7 mins for the back up process. There has been no excessive data that has been transferred into the iPhone in this period. Here's a screen shot, it hovers from 600 kbs (appr) to 0 and then back again. Previously it used to be a smooth constant 500 - 700 kbs throughout. Any ideas?
