Bmt Graduation Transition To Tech School?

hey guys! Corey left for basic training at Lackland AFB 6 weeks ago. only 16 more days left until he graduates! even though i can't be at his graduation since it's my first week back to school, i can't wait (: he's going straight to tech school and not taking a leave. during his last call he said that there's a "rumor" going around that the guys will get their phones back when they get on the bus to head to tech school. so my question is: girls who have had a guy go through tech school or is in tech school -- how long does it usually take for him to get his phone back between graduation and tech school??
