iOS 3.1.3 support

Okay, I have a bit of a problem here. Right now, I have an iOS app that I was working on prior to XCode 4.5.2's release. My macbook got stolen by a methodone addict, so I ended up getting a new one a few months later. I download the latest version of XCode, and what do I know? iOS 3.1.3 isn't supported anymore. So, my question is, is it possible to have two versions of XCode installed without them conflicting with each other?

You're probably thinking, "Don't bother with iOS 3.1.3, just use the latest version or iOS 5.1 at the oldest". I don't have a problem with that at all, it's just that I don't have any iOS devices that support that version. All I have is a iPod Touch 1st Generation. I'd be more than happy to buy a new iPod, iPhone or iPad, but I don't have the money for that right now. I'm unemployed, was homeless until fairly recently and jobs are rather hard to come by (even non skilled jobs have lots of competition here), and getting this app released will increase my chances of getting a new job and then I can continue releasing apps and make some cash on the side just in case I don't (assuming they're marketed well enough).

So is it a bad idea to have more than one installation of XCode for the sake of supporting my only (and ancient) iOS device? Thanks.

Okay, thanks alot guys. This really helped alot.

Unfortunately, I have one more problem. I can't download debugging support for iOS 3.0 - 3.2.2. It keeps giving me a 500 internal server error. Can this be downloaded manually?

EDIT: Nevermind, found a link for it here: http://adcdownload.apple.com/ios/ios_simulator__resigned/ios_3x_devicedebuggingsupport.dmg

EDIT2: Still not working. Keeps telling me that there's no device available that has a compatible version of iOS when I try to use my actual iPod. Simulator works fine, but isn't sufficient for my app which requires multi-touch.

Man, it sucks being poor and unemployed...

EDIT3: Fixed it. Turns out I had to unplug and reconnect the device.
