In-apps for journalists

[FlowStudioGames]

Do you know what journalist prefer when reviewing freemium games? We published classic premium game a year ago and now we are just finishing our first F2P title Sortee (TouchArcade thread). We don't know what is the common practice when reviewer wants to test "in-app gadgets".

Do they prefer:
1) some kind of cheat
2) Test User ID to play the game in sandbox
3) unlocked version distributed via Testflight
4) no one cares paying $0.99 to unlock the full content after a short trial.

What is your experience, do you have some insights from reviewers?
