French Carrier SFR advises users to avoid iOS 4 for iPhone 3G

iPhone 3G users who were tempted to upgrade to iOS 4 in order to use folders, Bing search, better mail, iBooks and other improvements in the latest operating system for iPhone are now wishing they hadn’t upgraded their device.

We recently reported that iPhone 3G running iOS 4 becomes slow and the battery drains faster. Apple support forum is filled with users complaining about slow performance, frequent crashes and now French carrier SFR on it’s iPhone software update info page warns users about sluggish performance:

updating of the iPhone 3G to software slows significantly iOS 4 navigation menus. Any update is irreversible.
This information concerns only the iPhone 3G and not the iPhone 3G.

According to a news story published by WSJ Apple is investigating this issue and it is expected to address it via software update.

If you can’t wait for Apple to release a fix then the only option is to downgrade your iPhone 3G from iOS 4 to iOS 3.1.3. The process is very simple and in less than 10 minutes you can make your iPhone 3G snappier just like before. CNET has posted a how to video showing the downgrade process.
