There is no 'hologram mode' on any iPad.
Settings - switch off airplane mode in the top left.
put it back in dfu and then restart it
No, im sorry, but ROBLOX is only used on the computer or on the Ipad, but the Ipad can only offline mode.
for sure
Put it into recovery mode and then re-install the firmware.
On iPad you get deflation mode
Yes, but only on extended resolution mode.
You can't I don't think :/
Yes, but only if the data set includes some negative numbers. For example, recording winter temperatures at the South Pole. They will all be negative (or most of them will be) so the mode and the median will be negative as well.
It's not good for anything that requires flash
The iOS 6 does not currently support panorama for the iPad. However there is an app called "360 Panorama" which is similar to the iOS 6 version.
