IPHONE 4.. is it really worth upgrade?

A couple of months ago apple came out with the new iphone 4. There has been rumors that there are lots of problems proven to be with it. For example there only suppose to last for 6 months before the software on your phone dies on you? This is all wrong rumors. Three of my friends have the iphone 4 and have told me that they havent had any problems with the phone what so ever. Here is a IPHONE 4 vs IPHONE 3GS review.
