Narrative:

During the climb while departing phl en route to bdr. We were receiving VFR advisories from phl departure control. At approximately 9500 ft we were told of an large transport at our 6 O'clock position. At roughly the same time our radar service was terminated. We continued our climb to 11500 ft and contacted ny center on suggested frequency. Before we 'checked in' we heard the large transport check in with ny center and complain he had come very close to another aircraft. The distance he reported was 1/4 mi. We then contacted ny center to request advisories. We felt that the large transport should have been given a vector or at least been told of our position, by the previous controller. (I think washington center). The fact that he was behind us and that there was a very widely scattered cloud layer made it difficult for us to see each other.
