While flying a VFR flight to LOM; I may have entered the Philadelphia Bravo airspace without clearance. I was communicating with PHL ATC on 124.35 for flight following. I was told to climb from 3;000 to 3;500 to avoid a TFR but don't remember specifically being cleared into the bravo airspace. Normally I would verify with ATC before entering the bravo if I was unsure. However; on this flight; my GPS equipment lost the GPS signal near Wilmington and I got distracted troubleshooting it. I was a few miles into the Bravo airspace when I realized I had not double checked the clearance. I was still talking with PHL ATC and they did not express any concerns with my location.
GA pilot reported inadvertently entering PHL Class B airspace without a clearance due to distraction from having to troubleshoot the GPS system on the aircraft.
