Hey, just bought and iphone 4 to repair, realized it was water damage (smells more like baileys to me) anyways im just going to sell it on ebay as is....now the model # is MC603C/A, I poked around the internet and this seems to be the model # of factory unlocked iphones, although itunes tells me the sim that came with it is not valid, im thinking it is just that the sim reader is damaged, but was wondering if anyone out there has a factory unlocked phone with the same model #? And i already checked the about menu and it says carrier is not available.
I think all Black 16GB iPhone 4s sold in Canada carry the same model number, it is not enough to know if its locked or not, given your observation i would rather think it is locked.
The easiest way is to try different SIM cards and see which one succeeds in activating in iTunes, the alternative is to jailbreak and hacktivate, then install SAM, SAM allows you to try different carrier SIM card ID prefixes, this substitutes the need to have actual SIM cards to try activation.
The FAQ has more details on using SAM here
With the bad LCD it becomes very hard to navigate through SAM, don't you think you need to fix the screen first.
Anyways, to help you test with the 2 SIMs, you can remove hacktivation by SSHing to the device and run the following 2 lines:
rm -rf /var/root/Library/Lockdown
killall -TERM lockdownd SpringBoard
A connect to iTunes image (if your LCD was good, this is NOT recovery mode) will show up, simply reconnect your iPhone to iTunes and it will attempt to reactivate.
