Hey, that was fast!

Actually I don't have any equipment, I'm not a pro like you, just one guy with a faulty phone that isn't worth much so there is no point in paying too much to fix it: if it is something simple ok, otherwise I'll just throw the phone away or sell the bits that work on ebay.

Thanks!

P.S.: Ignorant's question: why would the phone work at 900MHz but not at 1800MHz?

[pali]

6210 fixed with changing COBBA.
Now full network all is working corectly.
(it was 0 0 0 0 in netmonitor)

have here another 6210 with network problem.
Sometimes have full signal but never on startup.
if have signal not everytime can make call.
if i make call it interupts in speaker (but signal was full)

PA is new
As is new
26mhz also changed.
Any idea ?
