Hi guys, just got hold of 3gs, can use 3G and WIFI, it has imei, and it detects network, jailbroken/redsn0w etc.. Jailbroken with ipad baseband but can not make and receive calls, sms, etc. Whenever i try to make a call i am told "call failed" and when i attempt to send sms an exclamation mark appears as unable to send. Never any bars of connection appearing, 4.1 firmware, really need solving, any help greatly apreciated, many thanks, Kapslock
