I am currently a Straight Talk user with an unlocked iPhone 3GS and the phone and plan works great. I am wondering, however, if it is possible to for a GSM based iPad to work on Straight Talk. Based on my research so far, I have found that yes it does work. But the real question is, how can I get my iPhone "and" an iPad to both work on Straight Talk using the "same" plan? Can the Straight Talk SIM card in my iPhone be copied somehow and the duplicate SIM card inserted into the iPad? Or could I at least get my iPhone to tether data service over to an iPad?
