“I have now been trying out 3rd party applications on my upgraded original iPhone for just over 3 days and even though there are something over 550 applications in the iPhone App Store, there are a few select applications that stand out above the rest and I have several that now occupy a place on my main display. In today’s Mobile software Monday, I am presenting thoughts on my top 10 and a few others that are close to cracking my top 10 with a bit more refinement,” Matthew Miller writes for ZDNet.

MacDailyNews Note: Keep in mind that the lack of GPS is the first-gen iPhone that Miller has can possibly affect the list.

Miller’s list:

1. eReader – FREE
2. Super Monkey Ball – US$9.95
3. Evernote – FREE
4. SplashMoney – $9.99
5. Pandora – FREE
6. Facebook – FREE
7. Google Mobile App – FREE
8. Express – FREE
9. Twitterific – FREE and commercial version
10. PhoneSaber – FREE

“There are many other good applications and I have several more on my device. Others include eBay, Truphone (I need to deactivate my account setup on my S60 phone first), ShoZu, MySpace, Loopt, AOL Radio, Remote, Jott, and PayPal,” Miller writes. “I expect many more applications to be added as the App Store matures.”
