Apple To Unveil iPhone OS 4 On Thursday

Given all the attention on the iPad this weekend, this takes us for a bit of a surprise: Apple (NSDQ: AAPL) has sent out invitations to the media today, saying that it will be holding a “sneak peek of the next generation of iPhone OS software” on April 8 at 10 a.m. at Apple’s headquarters in Cupertino, Calif. In the accompanying image, there’s a reflection of the numeral “four.”

Potentially, the event could also discuss new hardware, which has a pattern of rolling out every July. The WSJ reported recently that two new handsets may be in the works, including one for the Verizon Wireless network. Another potential subject would be mobile advertising and how Apple will integrate the recently acquired Quattro Wireless.
