Tiffany Rubin had all but given up hope of ever seeing her abducted child again when she received an anonymous tip through her MySpace page. Someone had spotted her 7-year-old son and her ex-boyfriend in South Korea. The Queens special education teacher caught a 15-hour flight to South Korea on Sunday. She sneaked into her son's school, found Kobe Lee in a classroom, disguised him with a wig and sought refuge in the U.S. Embassy before bringing him home Wednesday. "It's great," Rubin said. "I never thought this day would come." Her ordeal began on Aug. 21, after her ex-boyfriend Jeffrey Salko disappeared with their child after a visit. At the time, he had joint custody of their son but was facing up to six months in jail for not paying child support. The boy lived with his mother and saw his father on alternate weekends. Kobe's court-appointed law guardian, Joseph Fredericks, had recommended Rubin receive sole custody.
