apologies if this has been discussed, I did a forum search and cannot find any info on this, at least for iphone 3G. I currently have USA AT&T data (3G capable) and voice plan on a samsung blackjack provided by my work. I would like to get this to work on iphone 3G. so I went out and bought an unactivated iphone 3G locally. upon opening the box, the screen shows a pic to ask to connect to iTunes, but only allows 911 calls. I then put in the SIM card from my samsung blackjack but it says "no service". I am pondering what my next steps should be. will the data and voice calls start working if I activate the phone via iTunes? or will it prompt me to activate by signing up for a new plan? or should I instead look to jailbreak this before I can use this on ATT's network? i understand there's currently no way to unlock with software right now. so I'm trying to figure out the options. looked into proxy sims but those are not very reliable. renewing contract with AT&T is not an option since this plan is not under my name. thanks for any help or pointers!
