iPhone Field Test Mode
July 27th, 2007 by ktula
For those that still have their iPhones and are having problem with dropped calls, you can enable the Field Test mode by entering this on iPhone’s dial pad:
*3001#12345#*
According to everettwolf at the Apple Discussion forum, once the Field Test mode is engaged, in the cell information area, you should see all the cell towers and their signal strength.
Wirelessinfo.com has more on it.
I have already returned my iPhone due to dropped calls so i am not able to verify if this actually works.
