You know we are huge fans of global sim cards and using VOIP on the iPhone to avoid expensive phone charges while traveling internationally. The latest app we have tried with good success is the Acrobits SIP Phone, $7.99. The app itself does not provide you any phone service. What it allows you to do is connect to your favorite VOIP provider be it Vonage or our favorite, Voip.Ms (See a brief summary of Voip.MS at the end of this review). There is a complete list of certified providers on …

I purchased an iPhone about a month ago and thought I would write about my opinions of the phone to date. Hands down this is the best “smart phone” I have ever owned. My recent phone history: Palm Treo 650, Palm Treo 750, HTC Tilt, and now the iPhone. I have no experience with any of the Blackberry devices so I cannot make a comparision.

LogTen Mobile, in our opinion, is the best logbook application available for the iPhone and Touch devices. If you are a Windows Mobile user we recommend Airline Pilots Daily Logbook program (APDL) by Logbook Pro. Now on to the review!
LogTen offers a typical well rounded iPhone interface. (See screenshots) It is very easy to enter, edit and view data. Most of the limitations with the program are due to how Apple allows programs to run on the iPhone. The biggest wish list item I would like to see and is …
