    My iPhone had to restored just now because I did a hard reset on it and it got stuck on the apple logo. Really, the only thing I did tonight was change the fonts a couple of times. Could that have caused the problem? I don't wanna have to go through all that again.

    It might give you problems if you're doing it thru SSH.
    Or are you using winterboard?

    It's only dangerous if you don't know what you are doing.

    The smart way to do it is:

    1. Make copies of the standard fonts in the "/System/Library/Fonts/Cache" directory so you always have them to reinstall. I leave the file names the same but I put a ".bak" on the end so I can easily tell what they are.

    2. I make sure that I can get into the iPhone with both iPhone Explorer and via an SSH terminal program so I can get to the backup font files and copy them back.

    If you do both of these things, you can always get into the iPhone even if it stuck on the Apple logo because of a font change gone wrong.

    I did it through SSH. I guess Winterboard is the safer alternative.

    You can't change all the fonts using WinterBoard. Well, I have not found a way anyway.

    I did both of those things. I couldn't connect with either of them when it was on the apple logo. That was the first thing I tried.

    EDIT: I didn't have afc2add installed, I just installed it, but would that make a difference? I could USB and SSH in before it went south, but I couldn't while it was sitting on the logo screen.

    yeap you messed it up w/ the font change because you didn't do the procedure properly or something went awry midway unfortunately...

    I have done some experimenting with font installs and have had my iPhone stuck at the Apple log several times. Each time I was able to open an SSH terminal session. This makes sense since the fonts load after the iPhone has booted.

    Well, I just tried it again and it reboots and comes back from a hard reset now. I don't know what I did before, but it seems to be working now.

    Do custom fonts cause it to boot more slowly? I only replaced like 5 files...

    They shouldn't. I replaced six fonts and noticed no difference in boot speed.

    Maybe I'm just percieving it to be slower since I changed something...

    Very dangerous?

    Sky diving is very dangerous. Trying to jump the Grand Canyon in a rocket cycle is very dangerous.

    Changing fonts on an iPhone 4 is barely qualifies as dangerous and only if you don't know what you are doing.

    Using the word dangerous in the title was a bit of a stretch. I was tired and I couldn't think of any other words. It's certainly not put me in any type of danger.

    i used fontswap on my phone (4.1), and THEN discovered that it's not 4.1-ready. seems to have changed nothing, but i cannot reset it. so, while everything looks the same, i have one problem (and i've been unable to fix it):

    when i open my calendar, often the text disappears. then i have to click from my default 'list' view to 'day' view, and back, and all is well again.

    ???? a minor annoyance, and making me think about restoring/re jb-ing again...

    I have enclosed the iOS 4.1 fonts likely to have been changed by FontSwap. Just copy them to:

    /System/Library/Fonts/Cache/

    Then you should be back to normal.

    iPhoneRuler is great because it has a variety of fonts and tells you how to install, step by step.
