iPhone newbie question: Used iPhone purchase tips

Wish to unlock and JB (un-tethered)

Thinking one would need a 4S (or 4) running 5.1.1 or older

Does base band version matter ?

Finding one already Jailbroken might mean Cydia has blobs?


Thanks and Happy 2013 to all!

best option is to check if it be unlocked via the carrier or grey market IEMI unlocks if it's AT&T by chance they are real cheap under $5 now. no unlockable basebands in two years. that should give you a idea.

Have been using a 3 unlocked/JB after running iPhone Configuration Utility.app in order to use ATT GoPhone sim (activated in another phone).

Would be hesitant to have ATT unlock (have heard they will for commitment free phones) since they only condone prepaid smart phone sims.
