I recently updated my 3G iphone to the latest software OS 4.0.1 using itunes on my new macbookpro.
I have an old laptop with an old version of itunes that refuses to update to version 9.2.1. The old version of itunes will now not recognise my iphone and have no way of getting my music and purchased apps onto my iphone. Can anyone suggest anything? Is it possible for me to install an older iphone OS back onto my phone??
