Did you hacktivate the phone, or use an ATT sim to activate it when you updated to 4.2.1?

If you hacktivated thats your problem

Right, hacktivation machine always try to get push authentic from apple' server, that means EDGE in using all the time.

Cell phone' EDGE/GPRS use same data channel with voice calling, so your phone can do one thing only at a time, either calling or connect to internet(not only browsing safari).

Normally, cell phone would break EDGE/GPRS when there is a call in, because it considers voice call priority, unfortunately, iPad was designed as no voice-call device, so no priority for voice-call.

because there is specific phone numbers that can call me and others that can't

There is 2 ways
1, Use a SAM tool, please follow this guide.

2, use an Official carrier SIM card to activate iPhone after an fresh restoring, and connect it to internet with Wi-Fi before Jailbreaking and unlock, that will get it a official valid push certificates, you can check for more information here
