As the title says my upgrade is up in 3 days and I'm wanting to upgrade from a 4 to a 5. My biggest reason for upgrade is: 1. 3G to 4G 2. New Factor 3. Lighter 4. Light use of Siri I could really care less about the the other features. The reasons to upgrade are pretty big to me although since mine is a work phone I truly can only upgrade every 2 years, so I want to make it count. Should I wait it out for the 5S or go 5?
