One possible solution to reception problems on the iPhone 4

Now also know as the walls, the iPhone 4 reception problems when you tighten the bottom left. From the USA but come the first possible solutions.

Some users confirm that removing and reinserting the microSIM, no longer have the problems mentioned above. This "fix" has been confirmed by several users contacted by MacRumors.

In practice it seems that the problems are caused by the contacts of the SIM, which does not fit perfectly within the compartment and cause the weakening of the signal.

Personally, I can tell you with my SIM Wind duly cut I've never encountered the problem of loss of signal. This is probably because of chip derives its conformation, different from the last trade SIM (my card back to 2003).

This is also confirmed by others: some have in fact cut the SIM so that the contacts did not happen inside the compartment, and the notches are moved from one to three, as they are missing the problems of signal loss.
We will keep you updated.
