Sprint released its latest 4G phone earlier this month and the launch price of $149.99 seemed surprisingly reasonable for a well-spec’d 4G smartphone with all the trimmings. As reasonable as that might be, the second smartphone in Sprint’s EVO line is now available from AmazonWireless for just $89.99 with a new two-year contract. The HTC EVO Shift 4G features a 3.6-inch 800 x 480-pixel touchscreen display, an 800MHz processor, a 5-megapixel camera with 720p HD video capture support, mobile hotspot capabilities and 4G WiMAX connectivity, as its moniker might indicate. It runs Android 2.2 Froyo and all in all, it’s definitely a solid option for Sprint subscribers seeking out a new smartphone. Then again, with Mobile World Congress less than a month away, it might be wise to hold off and see what new goodies Sprint has in store.
