Help with modifying advanced Katana attributes

Hey, something has happened to my phone (It is unclear what exactly happened)
but now my phone will not connect to my network
after looking through the Katana's menus, I found that SID, Channel, Technology, and Frequency all have "------" in their values
Since I am with solo (Bell mobility) my SID must be 16420, i believe i remember my channel as well, the technology is Digital and the frequency was either 1800MHz or 1900MHz.
I also know the reverse logistic code (##786#) as well as my MSL number.
Is there anyway to edit this data manually so as to avoid sending it in for 5-8weeks of repair.
Also, do you think that those shady phone unlocker people would be able to do it if i cannot? (i dont have a usb for my phone so i am relying on all of the cellphone sodes)
thanks alot

##3282# will get you into the 3G programming menu, but you need the MSL code, which can only be obtained by Sprint.

Also, you can try this. It came from a Sprint Programming forum, so this may not work with Solo, it may.
