When it comes to the sleek new HTC Inspire 4G for AT&T, we have good news and we have bad news: the good news is that it’s compatible with AT&T’s 4G network. The bad news, however, is that it’s not compatible with AT&T’s 4G network. Confused? Announced during AT&T’s 4G extravaganza this morning, the HTC Inspire 4G will be AT&T’s version of the Desire HD. It features a 4.3-inch display, Android 2.2 (Froyo), HTC’s updated Sense UI, an 8-megapixel camera with dual-LED flash, and it will be the first device in the U.S. to be compatible with HTCSense.com. The Inspire 4G will also feature compatibility with AT&T’s HSPA+ “4G” network. It will not, however, feature compatibility with AT&T’s LTE “4G” network. How inspiring. The HTC Inspire 4G will launch in the first half of 2011 at an unknown price point.
