Sorry if this is a repost, but I don't seem to be having much luck searching on my own. I currently have a Galaxy S3 on Sprint which I will soon update to the new CM10. I also use an iPhone 4s. The Gemini in me enjoys going back and forth (I test usable apps for work but hate carrying to phones), but once I install CM10, I will no longer be able to input the Sprint code to update the phone number and code to get it to work properly. Last time I tried, I had to restore my phone to factory in order to get my number back, then update the ROM again. Is there an easier way to go about this, something I'm missing?
