I managed to activate an old Iphone 2g while still under a Iphone 3g.
However, when I switched my original Iphone 3g sim back to the iphone 3g. I dont get data (no EDGE , GPRS, 3G) icon. In fact I cannot get data at all.
Do I really have to add back the iphone 3g data plan (more expensive) back on ?
I thought all data plans were considered equal?
