Narrative:

I was using VFR flight following from ZHU. The controller didn't switch me over to easterwood tower until exactly 5 mi away. After initial frequency change, I dialed the wrong frequency into my radio. After no answer, I looked up easterwood tower and changed frequencys. By this time, I was only 3 mi out before contacting the tower. As a result, I was already in easterwood field's airspace. I then was cleared to land but instructed to contact tower after landing. The controller then talked with me about the event that took place.
