Iphone says No Service, really urgent, can't attend calls or anything.

Hey guys, i just bought an iPhone, like 3 days ago, with firmware 1.1.3. I unlocked it with Ziphone and it was working fine, before the keyboard click noise stopped. I checked everything and nothing seemed to work. So i though of restoring the iPhone. By mistake i clicked the update button and without me knowing, the iPhone got updated to version 1.1.4. I tried unlocking it with Ziphone but it didn't help. So i thought of restoring it back to 1.1.3 but then i got this message after the restore was complete, so I used Ibrickr to get my phone back to normal mode. Then i again used Ziphone to unlock my iPhone, this time it took lesser time than the initial unlock and what i see is that the iPhone has been unlocked, jailbreaked and activated successfully except there is no signal. I have tried everything, downgrading to 1.1.1 and everything but it doesnot help. Please help as soon as possible
