Query: NYC Nextel i90c

First of all Nextel service is great in New York City (except Staten Island). I get reception pretty much all the time, only when im in the subway do i lose reception.As for the phone, I really enjoy it. I've made a few modifications to my phone with the help of an iden cable (around $10-$20) ideninsider.com and bubbasiden.com (both are free websites and give you information on how to add ringtones, make your keypad flash to your ringtones and a few other mods you can do)Its a great phone w/ great features and i am very happy with it.
