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!
