Few people in Germany pronounce Ivo EE-fo with the f-sound in the middle. Actually, this pronunciation seems to be common in Bavaria where most v-names (Valentin and so on) are pronounced with an f-sound. The pronunciation of such names is not regular. Many Germans outside and in Bavaria say "VULL-en-teen" instead of Bavarian "FAHLL-en-teen", whereas the name Eva is pronounced "EH-fa" everywhere, pronouncing the "v" like an "f". To come back to Ivo, the pronunciation "EE-vo" is much more common than "EE-fo" in Germany, although the reason is obscure. [noted -ed]
