As mention in the title, my 2G iPhone dont seems to be able to find any wi-fi connection at all. I tried everything. The problem starts even when i am using fw 2.2.1. And it seems to continue in the current fw. I even ask the Apple Store Genius when i was in U.S, and they told me that it might be due to the fact that i jailbreak my iphone.

As for the call problem , sometimes when someone is calling me, my phone wont even vibrate and the screen wont even show anything. Although everyone that calls, told me that they can hear the dial tone, but I dont seems to be able to receive them.

I have the same problem as well. I cant even connect to the free Apple Store wi-fi. And this problem have been going on for more than 2 months.

Well, i check online and there are three ways that is successful.
1 Send it back to Apple Sore if u still have warranty.
2 Put it in freezer for a couple of minutes, and your wi-fi could work for a couple of minutes to a couple of hours
3 Download and buy some wi-fi app.

So far, the results have been touch and go. It might work for some but not all.

I cant send it back to the Apple Store because mine is the 1st generation i.e my warranty died one year ago. And i jailbreak and unlock my iPhone. So that sucks for me.
