is there anyway to use any type of voip on a blackberry? I am forced to use a corp blackberry on t-mobile for work....they won't allow email on my current blackberry with verizon...even if i had a blackberry on t-mobile they would still require me to carry 2 blackberries...one for voice and one for email. i don't wan't to activate voice on my corp BB because i can't port my number to the new one and i DO NOT want t-mobile as my voice carrier...crap reception.
any ideas? i was hoping google voice would have an answer but it still uses the voice network to make calls.
