I've had my iPhone 3G since pretty much release day and I've not had one problem with it... until yesterday. Now I'm not sure if 02 was being a little weird yesterday or my phone, here's my problem. If I made a call (or someone called me) it was fine and we could both hear each other ok. After a couple of minutes though, the other person said that I started sounding like I was stuttering and they couldn't hear me, I could hear them fine but when I talked they couldn't understand anything. Since 2.1 I've had full 3G signal at home, the calls did this with 3G on and off so it's not that. This happened a number of times to a few different people. I've not tried it yet today but has anyone got any ideas? I've been running 2.1 since release, the phone is regularly backed up and only has a couple of apps on it.
Also - should I have a
3G sim card? I'm using the same sim I got with my contract 18 months ago. I've read somewhere that you will get a better signal with a 3G card? Any idea?
Thanks in advance
