Hi Guys -

I've got an iPhone 4s on 5.1 FW -

I'm currently stuck at the Activation page on the iPhone,

Ive read around and ended up finding a little bypass and found out the carrier is Telstra so i chucked in
my Telstra sim from my other iphone to try and activate the phone although it said "Only compatible SIM cards from a supported carrier may be used to activation iPhone" - "please insert the sim card that came with your iphone"

I dont get it seeing as im using a Telstra sim,

I bought the iPhone second hand and restored and updated it.

What can i do to get around this and begin using the phone?
