I have a few questions for the Sprint/Nextel Hybrid phone.. 1. If you already have Nextel, and a nextel phone, can you just buy a hybrid phone off ebay, and then take your simcard out of your current phone and put in into your newely purchashed hybrid phone. Or? 2. How does roaming work? Is it the same as all the other sprint phones? As in, does it allow for all types of digital roaming? How about analog? Will it roam onto Verizon, alltell, etc like the regular sprint phones do? 3. How about text messaging on the phone? Does it use Sprints text messaging service, or NEXTELS? I hope sprints, because Nextels is extremely slow and unrealiable when it comes to text messaging. I always text message my friend who has t-mobile on my sprint phone, and it's always instant. Although nextel's text messaging doesnt work half the time, and when it does, it's slow and can take hours, or days to recieve.
