iPhone cannot make calls/access anything

[hellonewyork]

This has happened to me before (twice). I have a jailbroken iPhone 2G v2.2.
I accidentally updated Cydia the first two times, causing it not to detect my phone service anymore and making me unlock it again.
However, this time, I didn't touch Cydia. I was just using the WiFi like always. Suddenly, it said the phone could not make or receive calls anymore. I restarted my iPhone, but this time, it wouldn't even let me access anything, it just told me to connect to iTunes.
What should I do? Please help!!!

Update to 2.2.1 first off, and then follow our guide here to rejailbreak/unlock the phone again. Updating cydia would not mess up the phone, it has nothing to do with the baseband. It must've been a coincidence.

Okay, thank you, I will try to do as the guide says.
Do you know why my phone would do this? Thrice?

It is probably just corrupted files. Are you jailbreaking using Mac or Windows?

 

[hellonewyork]

I brought it to somewhere to get it jailbroken, but I'm thinking they used Windows. That was only two months ago.

Well, if you have a Mac you should try using Pwnage Tool.

 

[hellonewyork]

Yup, I was going to do that.
Thanks for all your help! I hope it works out

Hey!
So I was all-set to follow the guide this morning, but when I restarted the phone, it suddenly started working again! I don't know what happened...
But now, only the apps don't work.
