An anonymous tipster has informed Phandroid that “RadioShack’s internal employee information system” shows that the HTC Evo 4G is heading for pre-order later this month and should be shipped early to mid-June.

Have you seen the Floridian appearance by the Evo 4G at a Sprint store? Regardless, thousands of geeks are head-over-heels besotted with Sprint’s Wimax super-phone and will purchase it sight unseen. Get your MasterCard or Visa information in hand and check in with RadioShack regularly because the Evo 4G is probably going to be tough to acquire at launch, unless you hurriedly and get your pre-order in.
