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?

Nevermind, 3g use in full effect.

Good way to lower your monthly data plan by 5 bucks!
