Liviu, if I am remembering correctly (being old and all) I thought if your get locked out you could clear the cache files manually on your server, and then you would be able to log in as admin. If that occurs...
with most browsers, when you log in the first time, it will ask if you want to save the password..some of your members are probably selecting 'no' , so they have to manually enter it each time
This issue is for me even in the App for some members :(((((

I can confirm with you that the upgradation of website and mobile doesn't relate with each other because they have the different version as well as specific improvements for the new release.
About the routine to upgrade the phpfox, we highly recommend all the users upgrade their site when the new version has been released due to in the new one, it will have new improvements as well as fix the issues in the old one.
good question I would be worried about the minimum age. without birthdate how do you know the person isnt 9 years old. That would seem to open up legal problems and is strange for Apple to have that positon.
BTW do you have a great phpfox developer that actualy answers and wants to be paid to do some site redesign?
I contacted some but its been days and no answer
I opted out the gender and DOB fields from admin > registration settings and made an appeal to Apple and got the App approved so I have the apps for android and iOS live now.
As for the age limit I only can write on terms and condition that we don't allow members below 18 years of age.
Further in the app I'll try to make some custom module where it says all the time that the profile is only like 20% completed and make the member to complete those details after registration.
Speeking about developers I don't use and don't look for any. I only use what phpfox provide as products and support.
I don't want to mix any developer work on the script as I don't have time and money to deal with incompatibility.
I only focus now to grow the community! Later on if I'll have revenue from this maybe I will hire a full time in house developer.
Please note that phpFox app does not support for iPads yet, so please do not submit for approval for Ipads.
Regarding your question, you can take screenshots with your current iPhone and then use a tool(for example Photoshop) to design for other required sizes.
