I have had 5 cell phones in the past 10 years, starting with the original MOTOROLA FLIP-PHONE.  Then I moved over to a NOKIA phone, which was okay, but I was not satisfied.  I moved over to the NEXTEL phone service for my next phone, which was the MOTOROLA i1000 and a couple of years later I bought the i90, which was the phone I have been using until I recently upgraded to the i730.  I have been with NEXTEL for the last 5 years and I am completely satisfied with their professionalism and outstanding service.  The trade-in/buy-back program is wonderful and it definitely the best way to upgrade your phone.  NOW........on to the i730.......WOW..........what an awesome phone!!!!!!!!!  I can't begin to tell you that NEXTEL offers the best MOTOROLA phones then any other carrier.  I have looked at other phones from other carriers and none compare to the i730.  If this is your 1st MOTOROLA phone purchase, you are in for a real treat.  The instructions are well-documented and it doesn't take rocket-science to navigate through the i730 software.  The biggest treat for me is the COLOR screen, the sleek-ness of the phone and it's overall aesthetic beauty.  So if want to be the envy of all your friends, please do yourself a favor and pick up this phone.  Also, once you experience the NEXTEL service, it will definitely be your last and only phone carrier.  PROOF:  I have successfully moved over many friends and family members to NEXTEL and I haven't heard any compliants.  ENJOY!
