If any one has purchased an i710 phone within the last couple of weeks and you have the R2b.02.02 software it will not accept a download yet. You will have to wait until Nextel updates their website with this latest software.
I found this out after spending hours trying the older versions (R2b.02.01 & R2b.02.00) and working with Nextel's Customer Support. The only conclusion that we could come to is that until they [Nextel] update their website Accutracking will not work on the phone. They could not give me a time frame of when this would happen.
Just thought that I would pass this on.
