iSpazio has put the white iPhone through its paces, and has documented the whole thing on video. They tested both the proximity sensor performance and signal loss caused by “death grip” in black devices. As you know, the rumor behind the white iPhone 4′s delay was due to issues with the proximity sensor and the camera quality among others things.
White Phone 4 exhibits excellent proximity sensor performance:
the white iPhone 4 exhibits excellent proximity sensor performance, responding immediately to turn off the device’s display when covered but then also keeping the display off until a finger or head is a “relatively large distance” away. The black iPhone 4s initially exhibited problems with displays coming back on while on phone calls, resulting in unintentional touch input. The issue was largely fixed in an iOS update, but it is reassuring to see that the white models exhibit solid performance from the get-go.
White iPhone 4 singal has been improved compared with black iPhone 4:
iSpazio also tested the “death grip”, attempting to generate signal loss by covering portions of the stainless steel band that serves as the antenna for the device. As with black iPhone 4s equipped with iOS versions released since Apple addressed early issues, the white iPhone 4 exhibits a slight drop in signal strength, but the drop does not appear to have a significant effect on connectivity.
All of those issues have been fixed and Apple has decided to go ahead and decide to release the white version of the iPhone 4. It is now officially on sale according to various reports around the web.
