iPhone 4 additional antenna option

[jpiszcz]

Hi,

It is supposedly an antenna booster...

Has anyone tried one of these with the iPhone 4?

There is a video here:

But he seems to be holding it in the beginning (no service) when he puts it down, it does appear to at least get a signal.

However, this is the only product of its kind, so there is nothing to compare it to, at least for the iPhone 4.

Any thoughts?

All this product does is add an extra length of wire to the external antenna aroun the iPhone. I highly doubt it does much at all if anything. In the video you can see that he holds the phone with the "death grip" before he puts the sticker on. Afterwards he leaves it alone on the table untouched. This could also have something to do with it. Also it would be quite annoying to have that sticker attached to my phone all the time.
