We report on the results of the search for extremely-high energy neutrinos with energies above 107 GeV obtained with the partially (∼30%) constructed IceCube in 2007. From the absence of signal events in the sample of 242.1 days of effective live time, we derive a 90% C.L. model independent differential upper limit based on the number of signal events per energy decade at E2ϕνe+νμ+ντ≃1.4×10-6 GeV cm-2 sec-1 sr-1 for neutrinos in the energy range from 3×107 to 3×109 GeV.
