I've been eligible for a iPhone upgrade ever since the new iPhone 4 was released, however, my husband cannot upgrade until the spring. I have been waiting on him to upgrade, because I know he'll be extremely jealous if I have an iPhone 4 before he gets one even though I've been using my iPhone 3 while he's working with a iPhone 3GS for years. I don't know how much longer I can wait. My phone has really slowed down ever since I've loaded the new software.
And, this weekend my husband's parents who like to save money more than they like to spend it just ordered two new iPhone 4's. They were eligible for the upgrade, and they did. We can't have older phones than his parents; we have to at least try to be cooler than his 'rents. Key word: try.
