for contacts, just export to gmail contacts if you haven't done so.

for sms, you can use sms backup and restore app (doesn't support mms though)

for whatsapp, install the whatsapp app in S3 but don't open it yet. in your S, open whatsapp, go to settings, under chat preferences, click "chat history backup". after that, copy the whatsapp folder from your S to S3, then only open whatsapp in S3. it will ask you whether you want to restore from backup, say yes.

same here. check with my colleagues, it's either the screen is blue-ish or it's yellowish. doesn't really bother me much though.
