Ok so, my friend gave me his iPhone cos he got a 4G one .. <- lucky >.<
And I changed the sim card with mine, which is Samsung or something.
So I clicked the reset button, and it reseted the media, settings, everything. So it powered off, and it turns back on again and says I have to connect to iTunes so I do that, only when i do that iTunes comes up with this message,
"We are unable to complete your activation at this Time. Please disconnect your iPhone from your computer and reconnect it later and we should be able to activate it. We apologize for the inconvenience this causes."
I tried it again after school like 5 hours later, but it STILL says the same message.
Please help, I need it on.

Appreciate it
