Will jailbreaking make my iPhone 3G function again?

Stupid Apple! They are forcing me to get rid of my iPhone 3G by killing off my apps, apps that I paid for! My daughter updated all my apps and now they don't work cuz the new version requires a minimum of iOS 5 to work and mine stopped at 4.3.2 or something. I always felt guilty about Jailbreaking but if it will allow me to use apps that are now not working I'll do it.

Yes they will

Yes, will work.

But that wouldnt be considered as original Iphone and also, if you
try to trade or sell the phone in the future, it would be worthless as
the price wouldnt be the same like what the original offers.

Yes and no.

No - you'll still need iOS 4.3.3+ or iOS 5.
Yes - You can get old version of the app off the internet. If its paid, you can find a cracked version. You paid for it after all. Be sure not to update though.

Although the 3g is getting old, and a second hand 3gs can be gotten for under 100 bucks if you look around ebay

  • Is it possible to make/ change the function of a cord? I want to know if it is possible to change the end of a cord. For example, let's say you have an HDMI cord and an Apple (iPhone etc) cord. Is it possible to maybe cut the two apart and wire the apple cord to the Apple cord so that the cord is HDMI to Apple? If there's any way to sort of "fuse" two cords together, please let me know.
