I have an unlimited data/text plan (with limited minutes) with AT&T, and I used to have a Samsung Impression (non-smartphone) and I now have an iPhone 3G running 4.1 (jailbroken with a redsn0w beta 0.9.6?)

Anyway, I was hoping there was a way I could fix the problem of not being able to use 3G on my iPhone even though I have unlimited data on my plan/SIM? It says "Could not activate cellular data network. You are not subscribed to a cellular data service." :confused:

I believe iPhones have a separate data plan that previous plans will not work on. You'll need to add an iPhone data plan I believe.
 
I thought if you made phone calls with it and AT&T realizes its an iphone, you'll automatically get enrolled in an iphone data plan after a while and if your dumbphone plan was unlimited, you'll magically get the 3G unlimited too.


I swear there are threads here about that, but I'm too lazy to search :cool:
 
AT&T does have a separate data plan for the iPhone. As tempusfugit points out, ATT will realize that you are using an iPhone and they will automatically enroll you in one of their data plans - probably retroactively. You should go ahead and call ATT and tell them you have an iPhone and have them set you up with the plan you select. Hopefully you can keep the unlimited data plan, but I think that you're going to be stuck with a limited data plan. Check out the available plans on the ATT website before you call them so that you will be familiar with what they'll offer.
