Last week we reported that T-Mobile had officially announced the Samsung Galaxy S Relay 4G, an Android-based handset with a slideout QWERTY keyboard. Unfortunately at that time, T-Mobile did not mention when exactly the phone would be released and just how much it will cost, but based on its specs we naturally assumed that it would not break the bank. Well the good news is that the price has been revealed and the Galaxy S Relay 4G will set you back $150 with a new two-year contract after a $50 mail-in rebate. It has also been scheduled for a release on the 19th of September. As a quick recap for those who might have missed the news, the Galaxy S Relay 4G will sport a 4” Super AMOLED Display, a 1.5GHz Qualcomm Snapdragon S3 dual-core processor, a 5MP rear-facing camera, a 1.3MP front-facing camera, HSPA+ 42Mbps support and Android 4.0 Ice Cream Sandwich preinstalled.
