I don't see the problem - I have spent hours and hours on this forum and I still have questions about ziphone, unlocking, installer app etc. There are many people out there who don't want to spend the time, energy looking things up that $10 or $20 is probably a real deal to have someone else do their dirty work.
Myself, I would much rather do the research and do it myself so I know how so the next time Apple comes out with a "revision" and it knocks my phone out, I will know how to redo it again .....but some people don't want to do that.
I would NEVER NEVER NEVER pay sticker for a new car because I really like haggling with car dealers but there are a LOT of people who just go in, pay retail and are happy.
To each his/her own I guess.
