Motorola i880 or i885 ??

I'm looking to replace my nextel phone and was looking on ebay for the i880 but i found out that the boost i885 can also work with nextel and it seems to be a little bit slimer than the i880. Does anyone know the differences between these phones and wich one is best?? Thanks
Answer: for a boost mobile just get a starter kit to unlock the nextel phone. Thats what I heard from a nextel representative
How do i upload my own ringtones..
I WENT THROUGH THE SAME THING. I WOUND UP BUYING THE i880, AND I LOVE IT. I WAS TOLD BY SOMEONE THAT I COULD JUST SWITCH SIM CARDS TO MAKE A BOOST PHONE WORK WITH NEXTEL, BUT I FOUND OUT THAT THE BOOST PHONE HAS TO BE UNLOCKED FIRST IN ORDER FOR THAT TO WORK.
BOOST PHONES AS FAR AS I KNOW ARE MODELED AFTER NEXTEL PHONES. I HAVE OWN BOTH AND HAVE FOUND NEXTEL PHONES TO BE MORE DURABLE. I HOPE THIS HELPED. GOOD LUCK.
