Apple banned fundraising apps for the iPhone, iPad, and iPod over a year ago (to much controversy) just as the first fundraising app hit the market through eBay/MissionFish. The field of software for fundraising as a result of the ban is anemic. Until this policy is removed it seems unlikely that major fundraising will take place via mobile applications. As the iPhone is the number one smart phone on the market developers have much less incentive to build software for fundraising purposes. It can be extrapolated that once the ban is lifted the fund-raising/development world will be playing catch-up for years.
Here are two notable successes/efforts to do fundraising through mobile apps over the last year:
eBay and Missionfish are on the verge of offering donation capabilities through eBay's mobile application for Android (it was originally intended for the iPhone). These donations should be relatively easy to put through and involves the user downloading the mobile eBay application and then searching for your cause. On the organization's end the donation item has to be set up as well as the account which will interface with paypal.
In the UK a group called Marie Curie Cancer Care managed to get around the ban by setting up an app that allows users to request donations from friends through text messaging. The application itself doesn't collect the funds but is party to gathering them.
