IPhone 4G review, price, features, how to round-file iOS 4

Apple’s latest release, iOS 4, is generally getting positive reviews. Not everyone’s been happy with it though.

iOS 4 is slowing some iPhone 3Gs down enough that users are abandoning the new operating system. If you’re still considering downloading the new iOS 4, waiting for reports from the first wave of users might be wise. Some like the lightning speed, others are downgrading to escape the glacial pace.

Some downloaders are already downgrading back to iOS 3.1.3. The new download is causing some iPhone apps to iFreeze.

Other Gizmodo reviews say otherwise, “Judging on the performance of both my and Mark Wilson’s 3Gs as well as based on anecdotal evidence on Twitter and support forums, the new iOS4 update is wreaking havoc on older iPhone 3Gs.”

“And what’s really to gain by updating? 3G owners aren’t getting multitasking, they aren’t getting wallpapers, they aren’t getting Bluetooth keyboard support. You’re essentially just getting app folders and threaded emails. Other than that, there’s nothing new. I went from having a slightly sluggish yet functional phone yesterday to an “updated” phone today that can barely handle the most basic of tasks, all with very little new functionality to show for it.”

Lifehacker has the lowdown on the download for those of you who want to can the new OS: “A lot of iPhone 3G owners—myself included—have discovered that upgrading to iOS 4 has slowed their devices to a crawl. If you decide the new features and shortcuts just aren’t worth the glacial performance, here’s how to downgrade your iDevice.”

Gizmodo says, “Day-to-day, the speed difference between the iPhone 4 and the iPhone 3GS isn’t that different. But in more intensive apps and games? The iPhone 4 smokes the 3GS and is nearly as fast as the iPad.”
