I have upgraded my 3G to 4S. So far, I love my 4S but I would like to keep my 3G without adding another phone number, keep using the applications that are still in it,use the internet thru wifi, add more photos from my computer and enjoy and ad more music. Will I be able to add/transfer more photos, music and update apps thru itunes? Will I loose any of them when I do this?
Yes you should be able to use your 3G. And no you shouldn't lose anything as long as you back up everything. But some apps may stop working on the 3G due to compatibility issues.
