I am uncomfortable to use iPhone in such configuration where top ear piece also functions as speaker. Going by Apple's recent software quality, I will always worry if the speaker volume fails to adjust and the speaker blasts off with full volume in my ears.
Maybe Apple has nailed the mechanism in thier software. But a simple thing like using a future iOS beta can cause it to malfunction and make you deaf.
