I can get my trusty R520 do make a DUN connection withh 770 ( even though it works great from laptop - grrr ) so I am trying to decide on a somewhat low-budget replacement phone. I've narrowed down my search to Nokia 6230b or Moto v635. I'm on tmobile but would like to have 850 for roaming.

I know 6230 works flawlessly - anyone have any experience with the v635?

Any other possibilities in the $200-250 range?
