How can i get installer.App on My iphone 3GS ?

Why do you need installer? If you’ve jailbroken it and have cydia you shouldn’t have a need for it. To add new sources in cydia you just need to search them and add them. I’d suggest re-jailbreaking it using Spirit. Hope that helps.

but i don’t have cydia :/

Ah. Well you’ll need to jailbreak your iPhone. What firmware do you have? 3.1.1 or something like that?

I have a jailbroken iPhone and it’s the greatest thing since sliced bread if u have downloaded cydia then you need to add sources to it etc… Just go to you tube and search for how to get installous!! That’s how I did it and my phone is perfect now every app for nothing! Hope everything goes well… Peace out

@Bugabear i have 3.1.3 :/ and @Danieljefferson mine is not jailbreaked it’s original :/ but im gonna try it anyways thnx

@FaithLambert In that case, use the Spirit jailbreak that I said above. It should jailbreak it and install Cydia. Then you just add whatever sources you want. And you should probably check before you buy that it has what you want on it.
