What if you've already developed a (simple) Android app for consumers, and you want to enter the iOS sphere as well, but you don't have an iOS dev on the (completely bootstrapped) team? Would it be worth investing one team member's time to learn iOS development, or outsource the creation and simultaneously learn to maintain/extend the code, or to simply go with PhoneGap despite the performance drawbacks?

It's not a question that can be answered without additional context, but thoughts on various approaches for this situation would be helpful and appreciated.
