Internet darling Kevin Rose and Twitter co-founder/CEO/Chairman Jack Dorsey (among many others) have been toiling away at Square – an iPhone credit card payment app coupled with a peripheral. The self-contained system e-mails receipts, donates a penny from every transaction to your charity of choice and unclutters your wallet of customer appreciation cards. The dongle attachment could use some work, but, man, the iPhone is being used in some ridiculously awesome applications.
