Are these phones any good as a cheap buy. What are issues with them.
I note that they are described as:-
3G and 3GS -- what is the difference and what "model" of iPhone would this be (Iphone 4 or 3 or 2 or what?)
Have 8gb and 16GB -- what is preferable GB and why
Phones are "Unlocked" and "Jailbroken" -- what do these terms mean. Are these all overseas sourced, not NZ new. Does that make them unusable on any NZ network? Can these devices be used overseas - say on trip to Australia or Europe/UK. Is unlocking or jailbreaking (of a phone) legal. Suppose this is OK as all the phones are made/sourced from overseas in any event - even those sold by NZ telecos.
OIS is -- 4.2.1 or 6.0. What is this and does it matter. One says OIS 4.2.1 is the most stable - is that right?
Phones are "refurbished" - does that mean they are reconditioned second hand and have also had any previous owner settings and PINS or passwords and/or downloads/apps etc removed.
Can one just insert one's own NZ prepay Sim Card into one of these devices and be "up and running"?
All and any comments welcome.
