I really liked the background image pattern used in testflightapp.com. It is so cool that I have replaced my all time favorite iPad-Safari-fabric texture to gray varient given below.

Here is the background image I am using for my iPad. It is looking gorgeous on Home screen.

Looks good on both orientations.

TL;DR

Apple version of the texture

Ever since I installed the iOS 3.2 SDK I was in love with the iPad/Safari background fabric texture.
