Hey I have two upgrades for my two lines. I was hoping to get the new iPhone 5 however, I was really hoping to get at minimum a 4 inch screen. Also I just recently sold my iPhone 4 so the iPhone 4S is not really all that appealing to me. I'll just use one of my lines to purchase and just sell on ebay and wait for the iPhone 5 for my other line. So my question is which iPhone will yield the highest profit? I was thinking of getting iPhone 4 since I'm speculating that I can sell it for $400-$450 brand new? That would earn me a gross profit of $300-$350. However if I purchase a iPhone 4S 16GB I am speculating that I can sell brand new for $700 or $750? Here I would gross $500-$550? However here also the higher sell price the higher Ebay fee. So what do you guys think will make a smarter choice to sell? I am guessing the iPhone 4S will be in great demand given that it can now be used any any carrier?
