My jeep has never had any issue holding an idle on a cold start. However, I had to clean up the carb with carb cleaner (big mistake). I sprayed it on the outside and shined it up (note jeep ran fine). Then a few weeks later, I decided to start it up and spray carb cleaner into the carburetor. Well, now my jeep will not idle during cold starts. I have to keep pressing the gas pedal and restart until it warms up. After the motor warms, everything is fine. HELP...

That sounds like you maybe dinged the choke linkage or that the choke decided to seize up. Spraying cleaner around only helps for looks, not running, other things you can't see still get dirty and jam up. A proper rebuild kit for it runs about $20.00.
I would be opening the air filter on the cold off engine to be sure the choke is closing after one shot on the gas pedal. If it isn't, then you need to find out where it is binding up. You need th one shot on the pedal to set the choke closed and to set the fast idle cam.
I have seen the choke thermostat shaft seize up on a few of them in the past even.
