I own an APPLE IPAD MC496TY currently on ios4.2.1 and bought it Italy. I currently can use it with the Etisalat 3G Network Provider in Nigeria as I currently there for visit. My question is this.... Can I upgrade to ios5.0.1 without having to unlock it to use the Etisalat 3G carrier in Nigeria because they do not have very reliable wifi hotpots and providers? Is my ipad factory unlocked? because I currently can't find any application like cydia or blackrain in it.... Thanks for your responses. Peace Ik.
