Upon jailbreaking, NtSpeed is only visible if I rotate my iPad to Landscape with a home button on the left. Any other orientation, I can see the NtSpeed box fly away to a position off screen.
However, after restarting SpringBoard a second time, then NtSpeed always appears in correct position in all 4 orientations.
Also, the location settings adjustments are extremely erratic and make it very difficult to position the bar correctly. It took me a week to finally achieve the perfect location:
Width: 40
Height 35
Location X: 5
Location Y: 49
These next two aren't as crucial but nevertheless:
Radius: 6
Alpha background: 0.50
Absolutely spectacular tweak BTW, I can't live without it!
