Hi - I recently made my old (2 years) 8210 SIM free (was on Orange, now on T-Mobile).
I am getting a problem with the signal in that I have full signal strength but, when I make a call, it suddenly drops to zero and drops the call. After a short time, the signal is back to full. This is happening pretty much in 90% of calls now!
I have read various suggestions on these pages to replace the antenna or flash the OS. What do you suggest?
The battery is new.
Any help appreciated!
