my phone will not pick up network, i have tried restoring on i-tunes and it comes up with error message -1

Here's what that error means:

Error 1 or -1

This may indicate a hardware issue with your device. Follow Troubleshooting security software issues, and restore your device on a different known-good computer. If the errors persist on another computer, the device may need service.

This comes from this article:

Apple support could probably help to a limited extent. First, try the "troubleshooting security software issues" suggestions from above.
