Hi, my husband loves his first generation iPad. It's getting more difficult now to download new apps. because his iOS version is 5.11 He will just have to get a new iPad.....It would be for WiFi only. His iPhone takes care of the calls. My question: Does any iPad (3.or 4. Generation) have a slot for a Sim Card for extra storage? If so, a 32 GB card would be plenty. I hope that my questions isn't redundant....have not found it under search. Thank you in advance for any answers.
