I arrive in Buenos Aires in the middle of June. Not sure wherelse I'm gonna go in South America yet and for how long but was wondering if it is easy enough to camp and is it dangerous? At that time of year Patagonia will be cold, how would I need to prepare for that?
Patagonia's too cold for camping roughly between mid april and mid november unless you have gear that is especially suited for cold weather. Mid June is the heart of austral winter (well, close to it); I recommend not going to Patagonia at all, and instead turn to the north west which is much more agreeable that time of year.
General comment on camping: a VERY bad idea when you're near civilisation, especially larger cities. You're prone to theft and worse. In the outdoors, of which Argentina has a lot, it is a very nice experience, albeit a bit rough for the lack of what us europeans consider basic campsite facilities (like toilets and running water). All in all, I personally wouldn't bother with camping, unless you don't mind having a lot of gear on you that is just dead weight while you're staying in hostels.
I believe lonely planet has a booklet on camping out in the wild; I don't know it, but it may contain a chapter on south america. They're usually quite thorough.

Since noone has replied yet, I will throw in my two cents. Camping in SA isnt like anywhere else. Argentina and I believe Chile or the only countries with websites for camping. But there are few of them as people prefer cabins. Brasil has camping but unless youre really really desperate, I would avoid at all costs. There are no showers and its not popular because get killed. Its not safe whatsoever. If you dont get killed, all your stuff is stolen (this is not a joke). There is one place here in Brasil that people do go camping that maybe ok is in Brotas in Sao Paulo State. Its a place for rafting, climbing and stuff but 2 years ago, a girl was raped and killed in front of her boyfriend. In Brasil, people dont even sleep on the beach as its not safe at all. Sorry about the bad news for Brasil, but I would rather you be informed.
Camping is quite popular in Colombia-most people live in cities in the mountains and love to jump in their cars and roar down to the coasts and enjoy a long weekend partying by the sea.
So there are a lot of places well set up for camping and lots of options.
That being said for one person without a car it would be tough, hotels can be found cheap and that's where you'll end up most of the times I wouldn't bother humping a lot of heavy camping gear around.
