I can upgrade sept 1st but my contract isn't up till jan 1st thru sprint. Been with sprint for like 5+ Yrs but LTE service is spotty and in general have trouble getting call when I'm in certain stores. I use an iPad to write orders when in stores and LTE (Verizon) is always on and in my area they get the best reception. So I was thinking of jumping ship in a few weeks get the iphone 6 thru verizon and just paying early termination fee. Few questions how much for opting out with 4 months left and also I want to keep my number so I should keep sprint active when the iphone 6 comes in thru verizon then what?, can verizon transfer number before I cancel sprint.
