Yes, and I went back to a new 32GB 3GS and couldn't be happier. All the antenna reception issues that you've heard of are true. WAY less comfortable to hold. Constantly afraid you're going to break it. Slides off of any remotely diagonal or angled surface due to new glass back. Push notification for email consistently fails. EMails that are marked as read are not marked as read. Sensor by the earpiece SUCKS - consistently comes back on when the phone is next to your face and you're engaged in a call so you're accidentally putting caller on hold, on speaker, pulling up contacts, beeping numbers in their ear, etc.. Steve Jobs' crappy and curt "Non-issue" reply. FaceTime will only work over WiFi. Pages take longer to render. Loses connection with Bluetooth devices you've used forever. Keyboard click sounds just suddenly stop working. Some people got volume buttons swapped. Some people report yellow discoloration on the screen. You need to invest in a case so you can actually use it as a phone - and for the first time ever, Apple has released its very own bumper case. How convenient!
GORGEOUS phone...remarkably ineffective. This does not "change everything all over again," so bub-bye.
