I wanted to know if i could change my Iphone 3gs for the newer model Iphone 4? It doesn't matter the cost, i just need to know if its possible as of 2012.
The quick answer is NO. That said, asuming you don't have a contract on the 3GS and it is in good condition, you could sell it on eBay for around $100-$150. Since a new IP4S (16gb) costs $199, it would then cost you slightly less than $50 to upgrade.
Even IF you have a contract, I would assume you're past the 18 month mark and are eligible for an upgrade.
A few months ago I bought a 3G for $100 and that was the low end price for this model at that time with several sellers asking $150.
