So I have this iPhone 1.1.4 that i found. I've jailbroken it and so-called "unlocked" it, but the SMS and calling only worked for a day. I tried restoring it and when i activate it on iTunes, it says the account on the SIM card is currently inactive(AT&T). I've tried many methods of trying to activate the phone, and so i bought a blank AT&T SIM card to see if i can get service with it, but it displays "No Service". What can i do now??? I appreciate the support guys.

If you're freshly restored pop a T-Mobile card, activate, and unlock again.. Should work.

return the phone to an AT&T store... it is blocked from use on the AT&T network.

accept a reward. be done with it.

so when you say a t-mobile card, can i just get a brand new blank one?
