Finally iOS 4.1 is out last week (9 September on Asia time) and I have upgraded. I have been waiting for this, hope it may have improved in performance on iPod Touch 2G.
iOS 4.1 need iTunes 10, and too bad that iTunes 10 says it only installed on Mac OS X 10.5 Leopard or above. That means it doesn't work on my iBook G3 (v2.2) which is running Mac OS X 10.4 Tiger. I have to do the upgrade on another machine.
iOS 4.1 try to solve a few problems and have some improvements like proximity problem, HDR (High Dynamic Range) photo... and security patches, my concert is the old iOS 4.0.x sluggish performance on iPhone 3G and iPod Touch 2G.
After tested for a few days on iPod Touch 2G, the sluggish problem still exist, may be not that often as before.
Another thing that I want to complain iTunes on Mac. iTunes came with few new features like iBooks, video playback... I can give up all those features, but I still need to update my iPod Touch (or iPhone) and iTunes is the only software to do it.
I expect to upgrade my iPod Touch using iTunes, be it iTunes version 9 or 10, as long as not limited to latest OS platform or latest hardware. May be iTunes should provide a lite version with limited features, since there are people complain on bloated iTunes, hope to have a slimming down iTunes.
