Top iPhone Websites that Apple doesn't want you to know about

In the past half year, since the introduction of the iPhone 3G, I gathered an amount of websites useful for iPhone users. I kind of all bookmarked them in one big iPhone folder, but now I finally managed to put some order in the chaos.

I've divided the bookmarks into Tricks & Tips, News, Development, Shops, and Hacking aka Jailbreak information. Just to make it clear: the last thing isn't illegal, but it's not something endorsed by Apple either. Even co-founder Steve Wozniak jailbroke his iPhone, because he -is- an engineer.

I will come to the other categories as well, but here is my list of top website you should know about using & jailbreaking your iPhone:

• blog.iphone-dev.org
  The official blog for latest jailbreak information
  
• NemusSync - sync between google and iPhone
  Synchronize calendar between Google and your iPhone.
• IPhone_Firmware_Download_Links
  Page that contains downloadable firmwares for iphone. Note that iTunes will also be able to download the latest firmware.
• MewSeek - SoulSeek client for the iPhone, iPhone 3G and iPod Touch
  This website is not yet up, will be the home of the MewSeek program that allows downloading music that can be played without having to go through iTunes
  
• Upgrade a jailbroken iphone
  Instructions how you can upgrade and restore all your jailbroken applications. I've tried it once but failed, but I will try it again for firmware 2.2
• errrick
  Homepage of the guy that made PwnPlayer and MewSeek
• IPodHash Test Data Contribution
  Page that is now challenged by Apple. It was set up to request information about different iPhone serial number, in order to hack the iTunesDB  hash functies. These are put in the Apple to protect DRM music, but also make it impossible to put music on your iPhone via Linux.
• gtkpod - a GUI for Apple's iPod using GTK2
  Website of the application that did the pre-2.0 firmware hack of iTunesDB hash.
• Main Page - WinPwn
  
  The windows application to jailbreak your iphone
• Brain Off » OpenStreetMap on the iPhone!
  Initial hack to replace Google Maps cache by an offline version of OpenStreetMap data. They give an example for London, but this could be a good replacement if you go abroard but do not want to do the completely unaffordable Data Roaming for Google maps on iPhone.
