For starts you must be on iOS 5.0.1 WITH A PRESERVED BASEBAND
There are plenty of guides on how to make a custom firmware with sn0wbreeze or redsn0w online
DO NOT UPGRADE TO STOCK 5.0.1
What you'll need:
-iOS 5+
-iFunbox/iFile
-Jailbroken iphone
-SAM or ATT SIM (SAM IS NOT NEEDED TO ACTIVATE iMessage/FaceTime, ONLY use it to Activate iPhone via iTunes)
1.Either activate your phone with SAM or ATT SIM (This must be done 1st before proceeding!)
2.Go to (CarrierLab.bundle or 00101 folder) /System/Library/Carrier Bundles/iPhone/00101/carrier.plist
-back up the file carrier.plist (just in case)
ADD ->
< key >PhoneNumberRegistrationGatewayAddress< string >+011447786205094< /string >
SET ->
< key >RedialOnRRCConnectionFailure< /key >
<true/>
---
3.Now go to /System/Library/Carrier Bundles/iPhone/Unknown.bundles/carrier.plist
Change -> All the 10 numbers you see under:
< key >PhoneNumberRegistrationGatewayAddress< /key >
SAVE NOW
Install TetherMe from cydia
Reboot.
You might have to toggle iMessage/FaceTime off then on, and leave it on then it will finally activate.
Your phone may freeze when iMessage activate so reboot if this occurs by holding the home and power button until the apple logo pops up
NOTE:
Remember every time you activate iMessage and or FaceTime it will charge your account additional $0.15 cents every time, because that's how much it cost to send an international text. So keep that in mind. As long as you keep these settings ON and never turn it off, it won't charge you, and it will stay activated. Re-Boots are safe!
