Hi,
I am in Belgium. My carrier is Base. My device is iphone 2g. (FW 3.1.2). Everything was fine untill I updated my mobile substrate on 9 nov 09 to the latest version(0.9.3087-1). I cannot make or receive a call after updating. It was just fine before installing mobile substrate. After installing mobile substrate I rebooted the device. Then it took a little longer than usual to get my carrier name. But when i tried to make a call it took a long time hanging and then i get ‘call failed’. Even though i could make a call sometimes but most of the time its not calling. And receiving a call doesn't work at, people are getting my voice mail.
Then I have jailbroken and unlocked it twice (today) with the latest PwangeTool 3.1.4. and restored it with the custom FW. So my baseband is still 04.05.04_G but I'm still having the same problem. Now my carrier is 'searching' for network for most of the time.
Some one please help me fixing this! Please!!!!
Thank you.
Someone please reply.
I am still having the same problem. I have restored my iphone many times by now but no luck

Is it a hardware problem?
What should I do??
