Sprint’s delayed launch of HTC’s EVO 4G LTE may be disappointing to eager customers, but this unforeseen hold up may prove to be an opportunity for retailers. A trusted source has shared some internal details about RadioShack’s approach to the delay, revealing that the Shack will be offering an instant $25 rebate to customers who pre-order the EVO 4G LTE, which will drop the device to $174.99, but wait, there’s more! If you happen to have the original HTC EVO 4G, RadioShack will also add an additional $25 trade-in credit towards your purchase, bringing your EVO 4G LTE’s price to $149.99. This deal is available to both new and existing customers and requires a two-year service agreement. Customers who have already pre-ordered the phone will automatically receive the $25 rebate.
