You CANNOT use 2 phones with the same number at the same time. But the Blackberry and IPhone uses different data plans. Every time you change the SIM card, you would need to notify AT&T of the change so that they can change the data plans to match the phone you are using.
First of all, be aware that all smartphones equipped with two SIM card slots come with a SIM manager. This allows the smartphone to manage its dual-SIM capability. For example, you can decide which SIM you want to mainly use, as well as manage their data usages separately. Depending on the manufacturer, there are options allowing one to associate a function to a SIM card by default, like which one handles outgoing calls or connects with 3G or 4G, for example.
