wait for iphone 5 and then get a 4 because they will be much cheaper
You should go to Apple store. They will repair it, if they couldn't repair, they will replace your phone with new iphone 4.
If you just recently got a new iPhone 4, connect it to iTunes and iTunes will identify it as a new phone. If you have previously synced your iPhone 3G with that computer before, then iTunes should give you the option to sync the new iPhone with a backup from your latest iPhone 3G sync. When you do that, your files from your 3G will be transferred to your iPhone 4. Hope that helps :)
If you are really looking for a place to find a cheap IPhone 4 whether the IPhone is used or brand new, then you should definitely check out the apple store.
The new iPhone 4 does.
Yes the iphone 4 is better so you should upgrade to the iphone 4.
Apple developed the iPhone
Wait! 5 will be awesome and 4 is...a 4.
No as its illegal.

Depends, if you really want the iPhone 5 then you should get it if you don't mind spending more money on it. I'd wait.
