I just had a few questions I needed clarified. Hopefully its not too much trouble. I'm in a family plan, and we all are eligible for an upgrade. I can get the iphone at the discounted price right? And concerning the data plans....I already have unlimited text on my phone. Could I just add the lowest iPhone data plan and be set? Also, does current iPhone 16gb owners feel as if they have enough space? Thanks, I appreciate you reading.
