I rely on my Iphone (3G) constantly. Because I rely on it so much, I have 2. Because of my needs, both are JB and Unlocked. Here's my question. I would like to buy a new one when they come out. I know if I sell mine now, it will be worth significantly more now than after the new release. But, I am worried that Apple might do something in the new Iphone to make it impossible to JB and/or Unlock. Then, I would just stick with my current 3Gs, and I wouln't sell. What is the likelihood of this happening? Any ideas?
