I was recently re-gifted a Samsung Galaxy S from US Cellular, but Sprint is my current cell phone provider (I have a Blackberry 8550 and absolutely hate it.) Since the Samsung Galaxy obviously doesn't use a SIM card since it's with US Cellular, I am wondering if there is a way to transfer my Sprint number to the new US Cellular phone so I can use that as my new phone. I don't really care about keeping my contacts or data from the Blackberry as long as I can switch to the new phone and start using it, but is there a way to switch over on a phone onto a Sprint phone number that is originally meant for US Cellular? Thanks!
