Ouch! iphone ios 4.0.2 not compatible with xcode 3.2.3

So i just upgraded my iphone 3GS to IOS 4.0.2 - that turns out to be a mistake if you use xcode 3.2.3 to create iphone apps. IT IS NOT COMPATIBLE YET. After reading more about what is in 4.0.2 vs 4.0.1, it appears that 4.0.2 only includes a change that keeps you from jailbreaking your iphone! I actually dont care about jailbreaking but it's a huge problem if xcode does not work!

Here's what you need to do to get back to 4.0.1. Search google for "download ios 4.0.1". I happened to find this site:
http://www.iphoneheat.com/2010/07/download-ios-4-0-1-firmware-for-iphone-4-3gs-3g-build-8a306/

and downloaded the correct 4.0.1 image for my 3GS.

Once the download is complete, open up iTunes.
MAKE SURE EVERYTHING IS BACKED UP!
Plug in your iphone to connect to your Mac.
Highlight your iphone in iTunes and go to the "Summary" tab.
Hold down the "option" key and click "Restore".
This should pop up window that will allow you to select the IOS 4.0.1 image you just downloaded.
BE CAREFUL!!!!!! MAKE SURE EVERYTHING IS BACKED UP!
Click ok to continue and follow the steps. Basically this will replace 4.0.2 with 4.0.1.
Once the IOS 4.0.1 is back on your iPhone, iTunes will prompt you to restore your files. Do this and your iPhone will basically be back to normal. Next iTunes will prompt you to upgrade to 4.0.2. CLICK NO!

The End of Solitude - Response to William Deresiewicz

I recently read an article by William Deresiewicz titled “ The End of Solitude ”. What prompted me to read the article was an interview with Mr. Deresiewicz that I heard on NPR. During the NPR interview, Mr. Deresiewicz delved into the importance of solitude, being alone and time for self-reflection. Of course, you are naturally drawn to premises that are similar to your own so I listened intently as he contrasted the present with the past regarding the lack of “alone” time that we all face today. Mr. Deresiewicz’s literary knowledge is beyond impressive – he’s an academic and is able to compare and contrast numerous thought-leaders of the past and their views of the value of solitude. In “The End of Solitude” he highlights the importance of solitude that numerous philosophers and famous authors have written about for many, many years. My personal appreciation for Thoreau’s writing, specifically Walden and more specifically “Solitude” and “Economy” immediately came to mind as I read
