As many if not all of my readers know approved iPhone developers are under a heavy NDA. This prevents public code discussions and step-by-step tutorials. One of the applications I'm currently working on heavily depends on the current users location. When I started diving into creating location based applications I naively assumed that iPhone's Core Location Framework would provide me with a rich API for getting country, city and street information. Well, that's not the case. At the end of the day all Core Location Framework gives you are latitude and longitude as a 2D coordinate. The rest is...


I'm sure you've heard that Google is going to offer a new Browser, called Chrome. Rumors about it have been out for a long time. Their new Browser - Chrome - is supposed to become available for download tonight (Tuesday 2nd, 2008) at the Chrome homepage (site is still down as of this writing). Google has asked Scott McCloud to draw a comic explaining key features about Chrome. The official link to the comic is here. The official PDF download link never worked for me. As I've experienced quite some downtimes and slow transmission speed with most of the mirroring sites,...

Quick note: Internet Explorer 8 Beta 2 breaks facebook Chat, Online Friends and Profile Videos. You'll constantly get JavaScript errors. At this moment there's a simple workaround: Go to Tools > Compatibility View Settings and add facebook.com to the list of sites. Henceforward IE 8 Beta 2 will render facebook in IE 7 compatibility mode. As a shortcut you can click the newly introduced Compatibility View Button right next to the URL in the Address Bar: This will immediately reload and rerender the current page in IE 7 mode. The button will only be offered when IE notices that it makes...

Update August 26th 2008: Dev Team has released the updated version 2.0.3.1 of PwnageTool which solves all the below issues. The remarks made in this post with respect to PwnageTool caused problems no longer apply. (For a preliminary potential solution see below...) Warning: I've received scattered reports that after upgrading to Apple firmware 2.0.2 with Dev Team's PwnageTool 2.0.3 a severe username and password issue arises in Mail.app and others. The symptoms: iPhone displays "Cannot Get Mail" error with "username or password is incorrect" even though you definitely entered the correct credentials. This seems to happen with IMAP and...

As always: To avoid version confusion: PwnageTool 2.0.3 supports Apple's official firmware version 2.0.2 (5c1) which as of this posting should be considered the current version of iPhone OS. Betas of version 2.1 have been made available to members of the iPhone...


I've received scattered reports that iPhones are stuck on the boot logo screen (Apple logo, pineapple or Steve Jobs) after a failed/aborted Cydia package install. The symptom seems to be that you select to install a package in Cydia, the installation routine starts and after some initial progress freezes your device. Once you try to reboot (by holding Home+Power for a while) the iPhone comes up with the boot logo and gets stuck. Even waiting "for hours" does not solve the problem. Multiple reboots don't help. Common to all reports is that iTunes no longer recognizes the iPhone once plugged into...


I've been asked by some folks with a .NET background how I've jump started my iPhone development journey. Well, first of all, if you're new to programing for the Mac and have a .NET/Visual Studio background, be warned: EVERYTHING IS DIFFERENT. And with "different" I mean VERY different. :-) The same applies if you're background is a Java/Eclipse one. It took a while for me to get a hold of Apple's paradigms when it comes to application architecture and how things integrate into each others. One of my biggest difficulties was to really grasp how stuff you...
