Should have got another 3gs... iphone 4 has given me a head ache!

Question

Ok so I had an iphone 3gs, for 2 years and it was great! It died last week from a fall. So I decide to get an iphone4, 32 gig.
So far, since I got it tonight, itunes has made me restore 4 times now. Not 3, but 4. Every time I get done, itunes shows the phone to be over capacity. There is no way as my 3gs was only a 16 gig and had around 10 gigs of free space.
I plug the phone back in, after around an hour each time for it to restore, and it tells me, “This computer has previously been synced with an iphone or another ios device”….. and to top it off it has refused to sync my contacts and calendar events… I know they are there, but itunes says there in nothing compatible on the computer for it to sync to…. Weird..
So if this last time does not work, ill send this back to Steve Jobs with my own instructions as to where it need be inserted and “Restored”… I thought about getting an HTC Droid, and probably should have.

Yes yes and yes! I had finished both the seasons and regular angry birds... And very very far through plants vs zombies.... Hehe all gone! Worst was my 3GS was JB and I could have saved it if I knew about the article u sent..
Live and learn!
So when 4.2.1 JB is out and I'm JB, Hopefully i wont need to do so, I now know how to save game settings.
I did search and searched on a "how to" get back the backup from the 3GS. I got a neat progie that reclaims deleted items BuT according to what I have read, iTunes does In fact write over the previous backup, if it's from a different iOS.. I have yet to find out why..... But I learned that setting the backup folder, and it's contents, to read only, it cannot be overwritten... Tho I do not do much upgrading, as far as ios's go, I'm ready!!
Thank you dbk9999 for the article!
