Bro i am using iphone unlocked via gevey sim, since the launch of gevey sim. Basically i bought a software unlocked iphone way back in october but in december i accidently upgraded it so it got locked. Well i have had good experience with it. It works perfect. you dont have to jailbreak to use it and you can upgrade it to latest firmwarte i.e 4.3.5 and gevey supports it aswell.
As far as i believe, even after the lauch of iphone 5, the price of iphone 4 would stay pretty much the same. What does everyone expect? Iphone 4 in 25k? lol right..
