Narrative:

I was flying my PA28-140 from my home base in cedar key, fl (cdk) to naples, fl (apf) with an intermediate stop at st petersburg albert whitted (spg) to pick up a passenger in severe clear VFR flight conditions on morning of dec/xy/94. My entire flight from cdk to spg employed flight following from ZJX and tampa approach. After a quick turnaround in spg with my passenger, also a pilot of 25 plus yrs with several thousand hours, I requested from the spg tower a sbound VFR departure, direct naples with class B clearance and an altitude of 5500 ft. This day, the ground and tower controller were one in the same as his exact instructions were, 'sbound departure approved, at or below 1900 ft, 125.3 for departure frequency' followed by 'cleared for takeoff.' I repeated the instructions back to the tower controller and received a correct confirmation from him on my readback. My passenger/pilot also heard the issued instructions. Headsets with an intercom were in use by both pilot and passenger. I departed with a standard pattern exit and climbed to the south with an onboard heading direct for apf and contacted tampa departure as I climbed through 1500 ft on the instructed frequency of 125.3. Tampa departure notified me that I did not have a class B airspace clearance and to descend immediately below 1200 ft and that I had also contacted them on the wrong frequency. I stated that I was following spg tower instructions and their reply was that the spg tower did not have authority/authorized to issue me a clearance into their airspace. I followed the tampa departure controller's instruction by descending below 1200 ft, contacted them on the newly instructed frequency, received a class B clearance and was approved for a climb to 5500 ft with my direct on-board heading. I remained on flight following for the remainder of the flight and terminate in naples (apf). This was the first time that I had ever violated a class B airspace without a clearance. I was following the instruction that I received from the spg tower.
