Quickest Way To Get Cash?
 

I want to get new guns in zone without using iTunes. I try to do ship repair and pick up trash, but those are all tedious. Any other ideas?

Invasions and Alien Rambo

You could always do those, or play showdown for gralats and base time.

Quite new to the game, where do you find those areas or places?

One is below the showdown building, one is up by sky base 1, one is below the skateboard shop, and one is to the left of Doodle's Rest Area.

As for Rambo, it travels between the nature shop and skateboard shop in a rectangle every 15 minutes.

Check your options, there will be an option for Rambo notifications, event PMs, or something along those lines; make sure they're enabled. Once they're enabled, you'll be notified when Rambo starts.

For invasions, however, you will just have to run around and see which ones have spawned.

Care to leave your IGN? I can help you out.

Also if you select the jobs button on your map, you can see where they are

I have nothing to say about this. Almost all jobs that are good in earning cash are just pk jobs.
Can you add non-pk jobs and I'll return to Zone?

I don't think you know what pk means.

I'd just collect trash since trash is easy to find.

Collect about 30+ of each trash before cashing them in.

No life trash pick collecting you can easily make 10k a day

Alien Rambo and Invasions are the quickest way currently to money in Zone.

Well, excluding gralat packs of course...

Collecting trash is a nice way to get money. Invest in a bike to make it faster.

Alien invasion/rambo and trashpicking all day everyday.

Buy a gralat packs, it's the quickest way to get cash lol. But earning cash, ah I suggest doing ship repair if you have patient and got nothing else to do. But if you like wandering around, pking and such I'd suggest trash picking, it's easy and it's everywhere.
