iPhone jailbreaking a new phone

[dadude77]

I've had my iphone for along time, and can't remember how it works when you start it up for the first time.

I was looking at buying a new iphone on ebay from x carrier (whatever, verizon, att, sprint) and unlocking it. However is it possible to jailbreak and unlock phone immediately from the box? or did you have to activate it somehow? also if iOS and/or baseband is too high of a version, could you take it backwards so you could jailbreak then unlock it?

Basically I don't want to buy a phone thats locked, and then have a chance of me not being able to unlock it, and being stuck with a phone i can't use

Do A LOT more research before buying your phone.

Need to know the firmware/baseband of the phone ur going to buy before knowing if you can jb or unlock.

You can only downgrade baseband on certain devices with certain basebands.

Give some detail on the phone youre looking at, fw and baseband, and we can go from there.

Edit: Actually. Yeah just buy a factory unlocked phone as trijethero said. Save everyone (urself included) a lot of time.

I agree if you don't want to learn then by a unlocked and save yourself allot of hassle. Also sounds like your more interested in unlocking then jailbreaking. just spend the extra cash you will be much happier in the long run.
