What is the BEST site to jailbreak my iphone?

Ok so like two years ago I jailbroke my Ipod touch 4th generation. I was scared out of my mind because I thought something bad would happen and it would break. Well it didn't and I was so happy. ( I jailbroke it from Green Poison.)So my ipod ran kinda slow when I jailbroke it and I couldn't figure out what to do with it once I jailbroke it. So I restored it. Now just recently I jailbroke it again but i did it from Envasi0n. Also I only jailbreak my things from untethered jailbrake. Ok so now i'm two months away from my upgrade and have decided to jailbreak my Iphone 4.it runs on IOS 6.1.1 I was going to jailbreak it from Envasi0n like my ipod but when i was figuring out new things i could do on my ipod touch i ran across a thing where i could get a windows 8 theme.well it didn't work with people that jailbroke their Ipod touch from Envasi0n. And I ran across another thing I couldn't do because it didn't work with people that jailbroke their Ipod touches from Envasi0n. I don't want to run into that problem so could someone tell me a Jailbreaking website that works good and doesn't have those same problems I had with Envasi0n? Also it needs to be free. Also can you recommend any FREE cool cydia tweaks. I know about Winter board and fake carrier.
