Thanks for your input, ca2l3vin.
Let me explain the situation a bit more in detail.
The phone was working fine, except for the coccasional loss of data connection in the middle of a download. In other words, until I relocked and reloaded the OEM ROM tonight, I was able make and receive calls no problems.
The problems I am experiencing happened right after I reloaded the OEM flash. Also, I haven't been able to reload any ROMs from the computer, I get RUU errors 320 and 328, so I've had to load them all from the storage card.
As far as signal goes, there simply is none whatsoever. The phone starts OFF, and when I attempt to turn it back on, it says "No Service". So I cannot make place any calls whatsoever.
It's quite upsetting
