Hey guys ! So I bought that iPhone 4 a couple of weeks ago. It was delivered with FW 4.0.2 and by mistake, I did the update to 5.0.1 So I'm kind of stucked here : The device has a 5.0.1 fw and a 04.11.08 baseband. And I checked with tinyumbrella no shsh saved from previous firmwares. I tried to downgrade it with the iFaith/Bluefreez trick but iFaith doesn't recognise any of the firmwares I download, so i dropped that idea and I just sat down on my couch, crying deeply So my iPhone is stucked on that activation screen saying that the SIM is not valid and "Only compatible sim cards from a supported carrier may be used to activate iPhone" message. I just want to use my phone as an iPod don't care if network's not working. So may I find a solution ? Thanks a lot for your help. Kind regards.
