We have AT&T & share 3gb. We both have iphones. Hers keeps dying on her randomly throughout the day. We did the replacement battery recall thing, which helped for a few months, but now it keeps dying daily throughout the day. She is just ready for a new one. So I bring up the old question...to go with the old 2-year contract or purchasing using Next? Our bill with her iphone and my iphone comes out to $122 after taxes. My phone was bought using the 2-yr. She is not the type to rush and need a phone every year. I assume if we bought hers using Next that I wouldn't be able to "steal" her upgrade in a year, would I? Thanks in advance.
