Hi guys,

i purchased a used iPhone last week. The previous owner told me that the wifi is not working due to something that happened during unlocking. I took my chances, and bought it. I am slowly running out of ideas, spent a hell lot of time reading through forums and googled a lot, still could not find any similar case.

Here are the symptoms:

Bluetooth and modem (Edge) working perfectly
Battery gets depleted very fast
Wifi is grayed out
Wifi HAS a mac address
Wifi CAN be turned on/off with netservices app (though it stays greyed out)
Wifi can be turned on/off along other baseband devices with "Airplane mode"

The phone originally had 1.1.4 on it, tried several restores with iLiberty X, i even sent it for repair to a shop (note that in Hungary iPhone is not supported, so it is not an Apple repair shop).

There they tried everything, even downgrading to 1.1.1, but eventually gave up and told me that it might be a hardware problem.

Before spending a lot of money on repairing i wanted to give it one more try, so here i am.

My only clue is that when i run iBooter to read out the radio nvram, this what i get:

Read 1536 bytes from nvram in 1488678 usec.

Anybody has any idea what that "Installing wifi calibration" line means?

I have run the same command when "Airplane mode" was on, and this is what i get:

radio readnvram

The only difference seems to be this "Installing Wifi calibration" line to me.

Anybody has any clues?

I have the exact same problem, bought iphone from a friend. Tried every fix yet nothing works...

Has anyone tried to upgrade firmware to 2.0 then downgrade back down to 1.1.4?? I'm thinking that might be my next move, or I'll try to return the phone to the apple store since its still under warrenty....Any other suggestions??

Hi,

I couldn't find a solution. I would like to go to the apple store. Do you know what I have to do before I give it to apple?

The phone is jailbreaked and unlocked.

Has somebody experience with returning a iphone with gray wifi to apple?

Thanks,
Mario
