Jarboe and Davis each posted $4,000 bail over the weekend.
Jarboe, of Ellenwood, Ga., was rated the No. 10 high school wide receiver in the nation by the recruiting Web site Rivals.com before signing with the Sooners in February.
He announced he was going to OU over Florida, Georgia and LSU on national television during halftime of a high school all-star game.
Sooner coach Bob Stoops hasn't commented on the charges, saying last Friday that "it wouldn't be appropriate until I knew exactly all the details and talked to the people involved over in that area.”
On Monday, Stoops said that he hasn't spoken with Jarboe since the incident.
Under Georgia gun laws, the penalty for being convicted of bringing a gun on school property is a fine up to $10,000 and a minimum of two years in prison.
In addition, federal gun laws mandate that any student found guilty of bringing a gun to school must be expelled for at least one year.
