Update 2: August 17, 2011 The TechExxpert guide has been updated to fully allow Xcode 4.1 to work. Sorry that the past fixes did not work. Thanks for the comments! Please let me know if this guide works/doesn't work.

Update: This guide has been modified to the latest updates as of August 2, 2011 including the latest Xcode 4.1 and OS X Lion 10.7.

Apple has been adamantly refusing to create an iPhone SDK support for Windows-based machines. Luckily, there is a work around to be able to fully run the iOS SDK and Xcode support for most all PC's.

The following steps involve installing a virtual machine on your PC, updating the virtual machine to 10.7 , then running the machine and downloading and installing the iOS SDK and Xcode on to the virtual machine.

There are other ways to install OS X on your machine but they involve creating a new partition and installing the Operating System directly to your hard drive. Those ways are much harder and have more confusing steps that could potentially damage your computer. This method is easier and safer to use.

The process will take 2-3 hours, but most of the time is consumed by large downloads. There's no software to buy or developer fees to pay.

Pull to Refresh, an innovative feature found in the latest Facebook update, is now available to download for the Mail app. The best part is that this app is completely free to use. Pull to Refresh is compatible with 3.x and iOS 4 firmwares.

To use, just slide your finger down in Mail app and release, your inbox will then update. To notupdate, just slide your finger back up, a really intuitive feature that really should be part of the standard iPhone UI.

Apple has dropped the prices on their website down 10% for many of their items. Mac's and iPads are all included in the discount. But no iPhones or iPhone items are on sale for the Black Friday sale.

Apple has officially released iOS 4.2. This update brings the long-awaited multitasking, wallpaper, and speed updates to the iPad. The device also covers the iPhone 4, iPhone 3GS, iPhone 3G, Second Generation iPod touch, Third Generation iPod touch, and Fourth Generation iPod touch.

If you're having problems updating to iOS 4.2, make sure that your iTunes is updated to the current version.

Jailbreak is not yet supported for this firmware. Updating to iOS 4.2 will remove the jailbreak from your device and restore it to Apple's original firmware. A jailbreak for 4.2 should be released in a few weeks at the latest. We may even see a jailbreak in the next few days.

Textfree has just been promoted with a beta release. In the beta release it gives you a very useful benefit that can drastically help you lower your cell phone bill. In the new beta,Textfree adds a new calling option where you can call anyone you want to using your iPod or iPhone for free.

If you have a iPod touch 4g you can use your headphones as the speakers and the video mircrophone to talk into so theres no needs to buy a headphones that come with a microhphones with it.
