In a promotional test to be run this weekend the Mobile 's  Galaxy S 4G will be taking on the iPhone on a download speed test with an estimated $1000 price on offer. All those who own iPhones  and they reside in Seattle area are requested to go and attempt to outdo the Samsung Galaxy in its download speed and win  $1000. In this contest the T-Mobile's Samsung Galaxy S 4G might emerge top because of its powerful 21 Mbps HSPA+ connectivity but the iphone  has less powerful 7.2 Mbps 3G radios which limit its power. This is one reason why the T mobile is offering such a high price because they are sure that it wont be possible to beat their phones at any time.
