How many failed attempts on iPhone 4 for RESTRICTIONS can be made? I reached 16?

1. Don't remember setting a passcode for this, and if I have it was by mistake and I don't remember it.
2. I've checked yahoo answers regarding this; they say 10 - before the whole data is erased, if it's set like this. I set this option for the phone passcode alone; wonder if it applies to the restrictions' one as well - doubt it because I've already exceeded the ten - there are already 16 failed attempts.
3. I may not need it if I reset the phone, which I might do sometime soon - but would avoid this hassle if I could!
4. Please Help - just tell me how many attempts can be made to retrieve the passcode for restrictions - and what happens if the maximum amount (if exist) is reached?
Might it lock the phone?

No, it doesn't lock the phone, make as many attempts you want to.
