Narrative:

I called phl approach about 30 mi west of the airport. Approach's response was 'aircraft, standby.' I continued flying east waiting for clearance into phl class B airspace. Flying by pilotage, I started descending and circling when I thought I was about 22 mi out. Approach then called me, gave me a squawk, and told me to proceed on present heading. Approach then informed me an large transport was descending for an approach behind me about 2 mi and they had to stop the descent until I passed beyond his path. The pilot of the large transport said he had me on TCASII. I was asked to call approach to discuss the matter. They told me I had already entered the class B airspace prior to clearance.
