Will you install iOS 4.1 when it comes out tomorrow?(if it comes out tomorrow) I'll install it on my iPhone 4 and on my iPod touch 2G. My iPhone has become noticeably slower as a jailbroken device. Just installed the GM a few hours ago, it may be just an impression, but the battery drains faster... But HDR is pretty cool. If the battery isn't as before tomorrow I'll downgrade and stay there.
