First off: recruiters need to get recruits, so of course they want you to enlist! Tell them no way. You want a pilot slot, put pilot, pilot, pilot. Getting into OTS was hard enough for me, but when I was there, I found it was harder as an enlisted guy according to the prior-enlisted dudes in my flight.
The requirement for reapplying is 180 days in between. Not "never". At least in 2004 it was for me. Same for the AFOQT. You might want to retake that if you need higher scores?
Absolutely look into the reserves and guard. They'll hire off the street. I had recruiters tell me I HAD to enlist and I believed them, only to learn at UPT that I was with guys that got hired with no flight time and no prior E time. Oh well.
Have fun with your flight training. It'll help your new AF package. You'll need new LORs and an interview (and maybe whatever else I don't remember). Also comb through you old package, b/c things might be wrong. My GPA was wrongly calculated as well as a few other errors were in there that once corrected, I went back with a much stronger package.
