Apple Holding iPhone 4 Press Conference Friday

Apple has invited the media to a special iPhone 4 press conference this Friday, sparking rumors that a recall may be imminent. The company hasn't said exactly what it plans to discuss at the press conference but the smartphone's much-discussed "death grip" antenna problem is expected to be the focus, PC World reports.

PR experts say Apple must recall the iPhone 4 to save its reputation, but many analysts say such a move, which would likely cost the firm over $1 billion, is unlikely. Apple is likelier to offer iPhone 4 buyers a free case to cover the reception trouble spot in the lower-left corner of the device, analyst Toni Sacconaghi told investors this week.
