IMessage - No SIM - Other Devices?
I have a jailbroken iPhone 4 with the SAM unlock in place, to fix iMessage and Push. I've never put a SIM card in the thing, and never plan to. After much dismay, (thinking the SAM fix wasn't working for iMessage), I found that it did work, but only for other iMessage users (I assume this because I just texted my own address and it worked).
Is there a way for me to be able to text other devices not running iMessage using this (or any) method?
