I did a live chat with Samsung about the same issues. They made me do a factory reset. I didn't think this was a big deal as I back my s2 up twice a week on kies. Once the reset was completed I hooked back up to kies to restore my phone and nothing came back. Now it shows it loading back into my phone from kies and it took like 20 mins to complete but still none of my settings or apps were back. I even lost things I paid for. When I go to the market all it says is you've already purchased item then it gets stuck and forces close my play store. My phone is constantly getting stuck where I need to shut down and start back up. I love the look of ics and some of the new features but gingerbread was a lot more stable. I'm wondering if the phone just simply wasn't designed for that big of a jump from android 2.0. Whatever to the new 4.0.4. I whatever it is I hope they fix it soon cause it's driving me nuts. :'(
