Ah, that wasn't clear - it just let me log in. Maybe I should have separate Apple IDs for my personal stuff vs. my development stuff...
agreed, right there with you. my main apple id is gmail, but i do already have a me.com account also. would like to merge but it seems the only option on the iPhone is to create a new one, not sign-in with an existing one.
Is your dev account on the same apple id as your mobileme account? My dev and mobileme accounts are different apple ids and I am assuming that is why I can't use mail...
