So I just got a replacement phone from apple 2 days ago because my WiFi stopped working. Now I have a different problem. In my house I usually get full bars on 3G but now with my new phone my signal just shuts down randomly and then connects back with full bars a few moments later. I don't know how to explain it well but I'll attach some screen shots to explain for me. Just notice the time and the signal strength. I'm using a 3G on 3.0.1 and I've tried restoring and everything I can think of. Anyone seen this before or know how to fix it?
