After I jailbroke my iPhone, my Push Mail, Calendar, Contacts and Bookmarks stopped syncing. The reason was because all my mail settings were reset. So I simply switched them all to sync. Didn’t work. I tried all kinds of stuff to try and get my accounts to sync from me.com, but nothing worked. Rebooted, toggled the switches a few more times… nothing.
What finally did it was to delete the MobileMe account completely, power the device off, power it on, and then re-add the MobileMe account. Sure enough, my iPhone was once again in sync with me.com. =)

Now that the new iPhone has been jailbroken, I’ve been messing around with all the images and icon, trying to customize the hell out of it. The first thing that I found out how to change was the background image for the dock (that metallic looking thing). The next thing that I learned was how to change individual application icons. (Within each app is a file ‘icon.png’, you just edit that)
Well, I came up with a new way to use the dock. I made all the app icons that are store in the dock blank PNG files (essentially no icon), and then made the background file one image with a bunch of stuff going on. All the notifications still appear where the icons were, and so do the text labels. For the text, I just made a black bar at the bottom faded out so that the text could be read.
Here’s a screen shot so you can see what I mean. My Apps at the bottom are: Phone, SMS, Safari, Mail.

I’m sure you could come up with a lot cooler ideas with this, but it should get the ball rolling =)

Have you been fucking around with your new iPhone and modding the hell out of it? Making your own graphics, hacking the apps, or seeing what happens when you edit a text file? Well, if you’re like me, you’re so eager to mess around that you forget to make a backup of something, and you overwrite it… with a bad file. SHIT! Now what? You could restore the iPhone from iTunes with the legit restore, or your custom IPSW file, but that takes forever, and you’ll loose a ton of your customizations. After having this happen to me twice, I decided to calm down and figure something out.
If you’ve downloaded the iPhone 2.0 SDK, it comes with a cool app called ‘iPhone Simulator’. In there are all the original files (even the encrypted PNG’s =)
The default install location is:
/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator2.0.sdk/
That’s the equivalent of root “/” on your iPhone. From there you can grab the originals and overwrite what you messed up on the phone =)
