Problem 3G signal going to EDGE when Unlock
 

Problem 3G signal going to EDGE when Unlocked. Several Blackberry phone when unlocked the signal 3G goes to EDGE. For example companies Verizon Sprint USA. Is there a way to correct this?? So that phone works with 3G or 4G

Unlocking with code not affect in some way blackberry phone.
This can be firmware limitation or some setting in phone.

Thanks I understand but is there a way to solve this. In my country theres a lot a blackberrys like this and could make some money fixing them

Most likely those blackberry support 3G cdma (gsm radio must support only edge), as sprint/verizon are cdma carriers

Yep if I program in CDMA they work in 3G but people want to use there SIM card in 3G soim triying to find a solution.

this goes into hardware of handset nothing related to unlocking or nck support
