This is so amazing, with all this modern technology out there and no, there is no way to move data from product a to product b? It seems that this industry is indeed stuck in a thick cloud (of how to make things extremly hard for customers who want to switch).
Jailbreaking an iPhone 4s would not be that easy and I personally do not like to do this.
Why can't apple step up and create a "easy to transfer everything on the android to iPhone" application and google could do it vice versa? With what we have now it is either forget your data transfer and be stuck forever or throw it overboard and start from scratch. This is IT from the stone age and not the fancy miracle pixie dust stuff that is printed on the sales boxes.
