I saw an article on PhoneDog this morning asking "How often do you upgrade?" (link here: http://www.phonedog.com/2014/02/07/how-often-do-you-upgrade/) So I was just curious to see how long others waited. Here's mine... Longest I had a Samsung Strive on AT&T from August 2010 to September 2012. Shortest 1 week in July 2010 (or maybe even less...lol) with a T-Mobile/Motorola Sidekick Slide on AT&T. The reason I kept it for such a short time is that since it was being used on AT&T, it couldn't access T-Mo's servers where every Sidekick owner's data was stored. Anytime the battery ran down (which was pretty often), my texts, pictures, contacts, etc., had disappeared. I got fed up with it and got the Samsung.
