2. Non-3G mobile network signal sometimes will drop by 1 bar
3. Pending 3G testing as my home has very bad fluctuating 3G signal
Final comments:
Biggest disappointment, the case bubbled my SP on the top. My iPhone is currently installed with PS Anti-glare on the front, Lucky Labs Carbon on the back and Lucky Labs Spectra Wrap around the phone. I am suspecting its caused by the carbon backing as it makes the phone slightly thicker. Will try to test it without my carbon back to see if it still bubbles. Even so I strongly believe if you stick a good quality SP which is thick on the front & back it will bubble on both sides. Next alternative? Get a thinner cheapo SP

Apart from the bubbling issue I am very happy with the overall outlook and built quality although it could be better as mine came with a few minor scuff marks.
Update: Removed Lucky Labs back carbon sticker and the phone slides in smoothly with out any bubbles 
Will I still buy a Vapor? Yes.
PS: If I managed to poison anyone, I have an extra Palladium Silver for sale. PM me for price. does this have the slot opening for access to sim card tray? sorta need it when travel need to swap sim card or else data charge roaming going to cost me a new ip4
