Input: San Francisco (CNN) -- As Nokia prepares for its next crucial venture into the U.S. and high-end smartphones, the Finnish cell-phone maker is missing a crucial piece: an abundant catalog of applications. Nokia is attempting to woo app developers with such incentives as pre-installing their software on the forthcoming phone, prominent promotion for their products and funding development of an app, according to three people involved in the negotiations. A vibrant app store has become a major selling point to smartphone customers. In the past, Nokia, which sells the highest volume of mobile phones worldwide, has made efforts to work with some creators of apps for its platforms. A Nokia spokeswoman said the company offers app developers a variety of incentives, some in partnership with Microsoft, which include coding assistance and marketing. "We do not disclose these arrangements, as each is different," she said.
