For anyone who still have an iPhone 3G and upgraded to iOS 4.0, you surely noticed how sluggish your iPhone's performance became. You may have even experienced the type of erratic behavior you'd expect from a 4.0 year old. Well iOS 4.1 has come to the rescue.
I tend to wait a week or so before loading updates so I get a chance to read reviews. Everything I've read, heard and experienced myself has been positive about iOS 4.1
The best quote I've heard is that "4.1 is everything 4.0 should have been!" I guess Apple can't hit one out of the park every time.
