Mac OS 10.7.1 Update
This is the first update after I installed Lion. It does not include any fix to add file size to Preview, as I want. I don’t think my voice will heard.

Updated to Xcode 4.1
oday I updated me Xcode to 4.1. It is a free version available from Apple store. That means you either have to have Snow Leopard or Lion if you want to get it. Before Lion’s release it was $5.00 from Apple Store. I have not started my iOS development for a while since I have been kept watching WWDC 2011 videos. Right now I am in the half way through 400 sessions and only 500 serials in my schedule. It is really good to learn OS and iOS new features from those session videos.
