I installed iOS 5 on my wife's iPhone 3GS about 3 weeks ago. When the process was over, she was missing her apps. I reinstalled these from the
App Store via the
Purchased section. However, she was missing data from her apps. At the time, it didn't seem like a big deal, because her emails were still on the server. Over the past few weeks, however, it has become more of a pain, from the trivial (lost Angry Bird levels) to the more major (lost appointments).
So, if I was to connect the iPhone up to the computer from which iOS 5 was installed, I'm thinking I could restore the data. However, I'm afraid that if I did so it would erase any data accumulated over the past 3 weeks.
So I have two questions
a) If I restore data on the iPhone from a few weeks ago, will it indeed erase data that has been accumulated since then? Is there a way to merge data?
b) Is there a way to restore data for only particular apps?
The end goal is to somehow retrieve all the data from before the iOS 5 updateand the data since the update.
