Saying to wait for the S4 price drop can be said for almost anything. Of course the price will start to drop once we are 2 quarters into the release of the next generation. Also, based on the AT&T announcement, the initial S4 price will be $250. Keep that in mind because its not a huge leap from the S3 which should be available for $50-$75 on contract soon depending on carrier. I hope the $250 is for the 32 gb one because pushing past the pricing that iPhone standardized of $199 is a mistake IMO.
Regardless if you want the S3/S4. $70 is not a very good price. It's been down to as little as a penny on occasion. And down to $49 multiple times. And that's before the next gen came out. These will be free.99-$49 all day in a month or so
