lol - i've tried resetting settings, hard resetting the phone, different APN settings, cleaning my sim card... nothing works!
Does the iphone not auto switch to 2g when it can't get a 3g signal? If I disable 3g manually then it gets almost full 2g signal - surely it should do this itself tho rather than sit with "no service"??
My 3G would seem to prefer a really weak 3G signal than a strong 2G signal. (And would also prefer to connect to a WiFi that had no active internet connection rather than using 3G).
Also I remember (July / August '08) lots of us were having problems with it dropping calls when switching from 3G to 2G.
