Currently, I have a SENA Ultraslim. http://www.senacases.com/apple/iphone-4s-cases/ultraslim/ I like it because it gives me some protection and keeps pocket lint off my phone, but I can still use my phone naked. I can also use my XM Skydock with no problem, as the Apple Bumper doesn't fit the phone. The only problem is it doesn't really protect the screen of my 4s while it is out of the case. I was thinking of getting the Zagg case friendly invisible shield and the Apple Bumper anyway. http://www.zagg.com/invisibleshield/apple-iphone-4-cases-screen-protectors-covers-skins-shields.php http://store.apple.com/us/product/MC839ZM/B?fnode=MTY1NDA0NA I'm hoping to get some protection on the screen and reduce fingerprinting, and still be able to use my iPhone 4s (essentially) naked. The only problem with this is my XM Skydock, which I use on a daily basis. I was going to attempt a dock extender. http://www.buyijet.com/checkout/cart/ Invisible Shield: $24.99 Apple Bumper: $29.99 Dock Extender: $12.00 Total: $66.98 Is this setup worth it to protect my phone without having to take the bumper off constantly?
