My iPhone was firmware 1.1.2 and I downgraded it to 1.1.1 to jailbreak and blah blah you know the rest. Well basically now ever since the jail break downgrade I cant make/receive calls and sometimes it periodically says something like "iphone needs to be activate," once I docked it after the downgrade it said it activated. In the top, left corner it says "No Service," and I can make no calls, not even 611 and no apps that work on EDGE work. Any idea how to fix this.
Got a tip for us?

iPhone not getting signal after jailbreak

First of all, an OTB (out od the box) 1.1.2 can't be downgraded in order to make/receive calls. You can only downgrade to jailbreak, install Oktoprep and go back to 1.1.2.
To make/receive calls you need also to downgrade the Baseband; however, that is not possible with the new 4.6 Bootloader.
I am having a similar problem. I'll explain it as best I can.
I had 1.1.1 jailbroken for a while. Everything was working great. Then I installed some Extended preference app from the installer.app source list. I think this was the problem. I had problems after a restart with a flashing white and black lined screen. So i put it in restore mode, and restored it to 1.1.1. did it again. installed that extended preferences thing and summerboard, restarted, got the same white black lines. so i said to myself, that must be the problem.. restored again, and only installed summerboard and bsd subsystem. happened again. so i figured i'd update to 1.1.2. restored 1.1.1, followed instructions to 1.1.2 from modmyiphone.com, and it was working fine. until i restarted, then it did this strange boot loop where it would stay at the apple, and vibrate twice every 8 seconds. so now i downgraded to 1.1.1 but i think i deviated from the instructions a littlebit and now i can't make calls. i can restore and wahtever as much as i want but it just tells me it's waiting for activation... i'm not sure what else i can do short of going to an apple store or and at&t store.

No Service after jailbreak
Any luck on fixing this RainManBK? I've experienced the exact same situation you describe. After jailbreaking the phone, I got the the vibrate/freeze issue. But after restoring, my iPhone (jailbroken) is working great but says "No Service" and I can't make phone calls.

PWNAGE reversed due to NO SERVICE
Well, I tried to be patient. But ten hours later, I gave up on thinking the phone would suddenly make calls again. Bummer.
I found a discussion on HowardForums about this, and it was suggested that I check the (by default, unchecked) "enable baseband update" option. I then unchecked the bootneutering stuff since I don't need that -- or really even know what it means. I also unchecked "unlock baseband" since I have an AT&T simcard/account.
So, the PWNAGE tool then built a custom IPSW with the baseband updated. Result: this didn't work either!
So I restored from the Apple IPSW, and I'm back in business again with AT&T. But of course, no third party apps. Again, bummer.
