Waiting for the nitty-gritty details about Verizon Wireless' long-awaited 4G network? Step back here after noon Wednesday, when company executives plan to dish out some new information on their plans for the major high-speed upgrade.

Palm shares jumped more than 8% in early afternoon trading after Harbinger Capital Partners disclosed Wednesday that it has taken a 9.48% stake in the struggling smartphone maker. For the noted hedge fund run by Philip Falcone, it's another bet in the wireless industry.

Verizon and AT&T are grousing about FCC conditions applied to its recent approval of Harbinger Capital's takeover of SkyTerra. The rules are designed to spur competition, and the two biggest wireless players aren't happy about it.
