Some iPhone users do not know that upgrading iPhone to the latest IOS will also update the baseband. If you would want to use other carriers, then you have to undergo the process of unlocking your iPhone. Nowadays, the most popular unlocking tool is the UltraSn0w, however, it does not support new baseband versions. Thus, for iPhone 4 users who want to upgrade to iOS 4.1, you have to take extra step to preserve the supported baseband, i.e. 01.59.00. Upgrading to the latest version (2.10.4) will make your iPhone unlockable.
Now, follow these steps to upgrade to iOS 4.1 without updating to the latest baseband version.

For example, there's Typing Speed Monitor which I recently posted. When you install it, you'll receive the following alerts:
There's nothing to fear, however, because your data isn't going anywhere: "[Typing Speed Monitor] can't give that data to anyone else because it doesn't have permission to access other hosts."
Still, the alerts are offputting and even give more seasoned surfers cold feet when installing an extension -- which is where the alert above comes in. Michael Gundlach, who maintains AdBlock for Chrome, used Chrome's extension update support to push a reassuring note to its users about an upcoming change.
I've seen the "requires more permissions" alert before from an extension, but I haven't seen a dev take the time to explain to users what's going on. It's a smart, thoughtful move by Gundlach. Until Chrome offers more insightful (and accurate) alerts, developers might want to follow this example to avoid accidentally scaring their users.
