Piracy exists, sure. But I would suggest that iPhone developers not worry about it. Anti-piracy measures for iPhone applications would require time and energy invested that would arguably be better spent improving the software.

Users who pirate applications aren't necessarily lost customers; they might not have purchased it legally even if they couldn't pirate it.

For an MMORPG, that IS a valid concern though. Pirated copies take up server resources and increase costs. Piracy also makes it more difficult to enforce rules - if everyone has to pay, closing a misbehaving account is feasible, but if a significant percentage of the userbase pirates it, then they can just make any number of free accounts, and degrade the experience for paying users.
