Can't start new conversation with GV number
Ever since upgrading to IOS 6 on my iPhone 4S (Sprint) my outgoing messages are using my actual Sprint phone number instead of Google Voice number which is causing confusion for my recipients. Priro to IOS 6 I was able to send/receive messages using my Google Voice number. The only way to resolve this is if I turn off iMessege but I don't want to do this. I tried changing the 'Start new conversation' number but it's not adjustable.
Any thoughts? I want to avoid turning off iMessage or using Google Voice app.
Thanks.
iPhone 4S, iOS 6
