Can Verizon phone work with Sprint?

I'll step in,

Due to the specifics of software loaded onto each different carrier's phone...No.

Hardware wise yes, you can do this, if you were somehow to find out the MSL codes for each phone (also called a sublock).

Since you have to hard code the programming on these. (Manually program, not OTA) you could do so with the sublock/MSL, but trying to tell the VCast to log into Power Vision, or vice versa, you are likely to make the software crash or not understand the information being sent/recieved, possibly frying your phone. Your voice calls would go thru just fine. Software on CDMA phones are more dependant on what the carrier's specific specs are, unlike GSM where the software is not.

If you are looking for a phone similar to the Samsung I730, I suggest purchasing the PPC6700 by UT Starcom. So far this has been a rock solid phone, EVDO speeds with also WiFi built in, 1.3 MP camera, and the new Windows mobile version.

BTW, employees that hand out sublock/MSL info can be terminated. Finding an unnatural ESN on the system is a lot easier to do now a days.

Better to give up the hassles and look at a similar phone that the carrier offers when it comes to CDMA.

GSM is different in that as long as the SIM lock is off, you can put any chip in there and use the voice side...but it takes a bit of programming to get the Data side to work properly, and in most cases, it doesn't work properly.

Anytime, the UT Starcom phone is doing great, hardly ever see this phone in my tech office.

I really like this Sprint phone and was considering getting it but i have Verizon Wireless and I really wanna know if I can have a Sprint phone but still be on Verizon.... I will try to get an answer and i will share.
Thanks.
