So managed to Jailbreak my iPhone using redsn0w, installed Cydia and installed ultrasn0w 1.2.5 for the carrier unlock. However, when i start the phone i get either "No service..." or "Searching" where my service bars should be.
Attempted to restore 5.0.1 FW via. iTunes, jailbreak and re-flash the Baseband with redsn0w to no avail.
Any ideas/help greatly appreciated! =]
