VoIP on 3g networks

It is interesting if skype will be making any deals with 3g wireless network operators to offer their services or a 3g companies will offer a cheap long distance voice calls to the customers.

Well friend, I am trying to find out if skype/voip will work on 3g networks using a blackberry or any other 3g phones over a data plan through T-mobile. It is $30 dollars a month for unlimited data. Did anyone tried making calls over 3g networks? If any one have any experience on this issue then plz let m know.

LOOKING FOR VOIP OVER SRINT DATA / RAZR V3M.
SHOULD I GET A DIFFERENT PHONE PERHAPS?

THE FOLLOWING MANUFACTURER'S DESCRIPTION WAS PASTED FROM:

https://developer.sprint.com/view_d...do?device=77895

PLEASE NOTICE UNDER Java packages Supported:

- Web Services (JSR-172): No
- JTWI (JSR-185): No

WOULD THIS BE THE WHAT WOULD BLOCK VOIP APPLICATIONS SUCH AS SKYPE, ISKOOT, NIMBUZZ OR OTHERS? WILL I ALSO NEED A WORK AROUND OVER OVER CDMA? SHOULD I CHOOSE A DIFFERENT PHONE? ANY ADVICE ON SPECIFIC VOIP PRODUCTS?

THANX

Additional Information Launched

Steve Jobs From Apple Included In His Speech At The Inroduction Of The New Iphone That "voip Packets Would Be Blocked From The Att Network. Verizon Has No Unlimited Data Plan. A Member Of The Sprint Technical Support Team Told Me Over The Phone That There Were No Restrictions On Voip Over The Sprint Network.

I Just Got My New Phone And Perhaps Need To Exchange It For A Different Model. I Got The Razr V3m.

However, Sprint Uses Brew 3.1 Which Requires Developer Registration With Qualcomm Before Sprint Allows Apps To Be Downloaded And Controlled By Sprint.

Additionally, I Seem To Finding That Gprs Technology Is What The Voip Providers And Apps (skype, Cellity, Iskoot, Nimbuzz, FRING, Etc) Use, With Only A Few Phones Listed At Iskoot For Cdma Compatibility.

I Also Want To Save $$$$ Using Voip And Am Looking For Advise As Well.

Thanx
