With SAM, you need to use a SIM card that is from a different carrier to the carrier your phone is locked to. This is generally the SIM you normally use with ultrasn0w.

My understanding is that Find My iPhone requires on BOTH push notifications and mobile.me push mail to be working.

Glad it worked, also - as push doctor solved your problem, if you feel generous - please feel free to donate to push doctor see [cmdshft] - blog - the donate link is at the right under the number of remaining certificates.

Could this issue rise if the phone is jailbreaked? I think this app can be pretty useful. I've seen s a bunch of Find my iPhone stories here, but I want to know if this app works if the factory defaults are activated...
