I have slowly but surly transitioned over from my carrier cell phone AT&T work # to my Google Voice # and I LOVE IT. I can SMS on my iPhone, iPad, online and it works awesome! On my iPhone I have an SMS Extension that sends SMS as my GV #, best $1.50 I spent in my life. When I make calls, it prompts me to call from Carrier or GV. Now with iMessage texting to other iPhone users, it is nice the conversation is streamed on all iDevices but I can't text online like I do with GV. There are advantages and disadvantages to both... with GV I can't SMS 100%, with iMessage you can for Free. With GV I my iPhone can be syncing on my computer with iTunes & I can text back and forth online away from my device... Anyone else having a similar 1 step forward and 2 back now with iMessage & Google Voice?
