how do most people pronounce the first sound in Oedipus?

I learned to pronounce it /'EdIpus/ (with /E/ as in let /'lEt/ and /I/ as in two-bit /'tu,bIt/), but during my stuffy phase in college I took to pronouncing it /'id@pus/ (with /i/ as in machine /ma'Sin/ and /@/ as in schwa). The former tends to be US English and the latter British. Hyena, I've always pronounced /haj'in@/ (with /j/ as in yeast /jist/).
