I personally use PayPal and like many users I am always happy to see upgrades to my mobile apps. Â The 2.0 update to PayPal on the iPhone added support for Bump Technologies. Â Bump is a product that allows you to quickly share contact information by bumping two phones together. Â Now you can bump phones to exchange pay for items or send money to a friend. Â Personally, I am not a huge fan of anything that makes it easy for me to part with my hard earned cash but it is cool technology. Â I personally use PayPal for most of my online purchases from non mainstream sites. Â I have used PayPal to donate to a developer, pay for software, or exchange money with friends. Â The user interface has been cleaned up but the major change is support for Bump.
