Harper Collins has ported its Browse Inside service to the iPhone. People using the iPhone can visit http://mobile.harpercollins.com and view the first 10 pages of chapters one and two of selected books (there’s 14 in the pilot), and then click to buy the book or pre-order it from a list of retailers. The same service is available for Flash-enabled devices at http://harpercollins.com/browseinside—both sites runby LibreDigital. The iPhone specific site was required because the device doesn’t support Flash… and this sort of thinking could be what gives iPhone a boost. Harper Collins probably doesn’t get a significant amount of revenue from its mobile sites—enough to put up a general mobile site, but not enough to port it to every handset. However, the iPhone has enough hype and street-cred that the publisher figured it had to be available on there, and this attitude is likely to be reflected in many companies...which will give the iPhone a significant content boost.
