Perhaps trying to steal some of the thunder from the many announcements scheduled for that day at Europe’s Mobile World Congress, AT&T will release its HTC Inspire 4G Android handset on February 13th, according to someone familiar with the plans. The CES-debuted Inspire will only cost $99.99 on contract, after a $50 mail-in rebate. With most high-end hardware launching at around the $200 mark, we have to wonder if the relatively low price is a tacit admission that this model is a rebadge of last fall’s Desire HD — whose aging specs would have trouble going up against Motorola’s Atrix 4G and Samsung’s Infuse 4G on an even playing field. Atrix is also expected in February, although it’s not clear when Infuse will ship. All three models will have to compete with four LTE-capable smartphones from Verizon in the near future as well.
