Many of us already have text messaging plans (I know I pay $14.99 for just my text messages). Since the iPhone plan already offers text messages, what do we/I do? I assume go ahead and activate the iPhone, keeping my current voice plan (I SO hope the rollover minutes don't disappear!), adding in the iPhone plan, and then going back to ATT.COM and deleting my current text message plan? I know I'll find out come Friday, but thought someone might have more insight. Thanks!
