need to activate phone but I dont have an authorized sim

[minkss]

Hey! So my phone is on the latest update, 4.3.5 i think, but I need to activate it, what can i do? I don't have an ATT sim...

Buy the SIM. Or hacktivate with Redsn0w ... but this jailbreaks the phone which means you'll have a tethered jb. You'll basically have to run redsn0w (yes this means you'll have to have a computer nearby) every time your phone shuts off or reboots. The jb on 4.3.5 is also quite buggy. So I wouldn't recommend jailbreaking/hacktivating. It's best to buy the AT&T SIM. It doesn't have to be active.
