Hello out there. Probably a very stupid question but my 3 year old iphone is getting slower and slower and behaving in a very strange manner altogether. I sync it regularly on to my macbook so my question is.......if I get a new phone and plug it into my computer, will everything in my address book be transferred on to the new phone automatically. I have absolutely no idea how to check whether the address book is actually stored on itunes, so can anyone tell me how to do that? Thank you.
